Cheers. According to the producers, when Diane Chambers left, Sam's character became Flanderized, whereas his womanizing was a sign of weakness and a reaction to sobriety, it became a nutty quirk (and his alcoholism all but vanished.) They also noted the show began to depend on physical comedy too much (such as Carla being literally blown sideways by strong wind.)
Dave Chappelle came to loathe how people started showing up to his stand-up comedy exclusively to demand that he replicate skits from his TV show, specifically the infamous Rick James one. This even led to a nervous breakdown, ensuring that the third season (or any after it) of Chappelle's Show would never get finished. And then there were the people who would yell at him, "I'm Rick James, Bitch!" (including one who apparently did so while he was with his family). Took about two minutes for him to feel Dude, Not Funny!. The significant Misaimed Fandom from his sizeably white audience who were there simply for the Uncle Tomfoolery and completely missing how Chappelle was satirizing and mocking such attitudes didn't help matters much, either.
Eddie Murphy refuses to acknowledge his old Saturday Night Live characters (Gumby as a faded, Jewish comedian, Mr. Robinsonnote a squatter and petty thug who hosted an inner city take on Mr. Rogers' Neighborhood, Buckwheat, etc), though they are some of his most enduring legacy.
It's probably because of a 1995 "Weekend Update" sketch in which David Spade, as part of his "Hollywood Minute" segment, made a brutal Take That at Murphy's (then-)lackluster career, saying "Look, kids, a falling star! Make a wish!", that reallypissed Murphy off.
Spade got a taste of his own medicine when Steve Martin showed up on "Hollywood Minute" unexpectedly and simply said "Hey, look at me! I'm a guy who's never had a career making fun of people who have!". The audience, who had been finding Spade's rants too mean-spirited, cheered their approval.
With the exception of "On Thursday We Leave For Home", Rod Serling wasn't happy with any of the episodes from the fourth season of The Twilight Zone. He felt that making the episodes an hour long (whereas the episodes from the previous three seasons had all been a half hour) did nothing but unnecessarily pad them out and make the stories less tight, and only returned to do the fifth and final season with the stipulation that the episode run time was reduced back to a half hour. To this day the hour long episodes are hardly ever shown in syndication, and season four is the only season of the series that is completely unavailable on Netflix.
In fact, the author of I Am Not Spock not only went on to write I Am Spock, but also has now officially become the original cast member with the longest on-screen association with the franchise, with his role in the 2009 film.
Robert Beltran (Chakotay) made disparaging comments about Voyager for years, even while the show was still running. He's often criticized the quality of the writing, the technobabble and the fact that he wasn't given a whole lot to do over the series' 7-season run. He's also expressed sincere disdain for the character of during chats with fans. It's believed that Beltran was given an out-of-nowhere relationship with Seven of Nine (aka Jeri Ryan) by the producers in order to shut him up long enough for the show to finish....or perhaps revenge for Beltran throwing fits over Jeri stealing his screentime!
Doc Oho: "Its important that you watch Robert Beltran’s performance very carefully in this episode because you can see an actor who has completely given up on the show he is tied to. He doesn’t just sound bored, he’s practically comatose and doesn’t bother to inject any emotion into his (admittedly functional) dialogue. Even when his face turns to goo he barely registers any pain or response....'The Demon class planet! One of our more interesting missions!’ – proof that even as a replicant Chakotay still talks absolute bollocks."
Jeri Ryan herself was an example who has come around. She initially had to be dragged kicking and screaming to the audition because of the record Trek has of typecasting actors and because of a bad experience catching a rerun of an earlier episode one night. She finally relented and got the part, and signed on for a three year deal. She initially planned to split the second her first contract was over, thanks in no small part to tensions on set with co-workers (not to mention that damn suit.) However, her mother was diagnosed with breast cancer, and she wasn't sure what kind of medical bills were about to come her way, so she agreed to stay on for a fourth season, which ended up being Voyager's last (her mother made a full recovery.) After the show, she stayed away from conventions, again to put some distance between her and Seven of Nine before type casting set in, and then was kept away because of problems with stalkers. Once this was explained, and precautions were taken in terms of security, she's began appearing more and more.
Brannon Braga quite justifiably hates the Voyager episode "Threshold" (as do all the cast and most of the fanbase) - to the point it never happened, complete with later Discontinuity Nod. Equally, the TNG first-season episode 'Code Of Honor' has the same thing.
Jolene Blalock takes a similar tack with Enterprise, or at least the series finale. In fact, several members of the cast (including Scott Bakula, Connor Trinneer and Blalock) joined the chorus blasting the show in media interviews in the months following "These Are The Voyages", which was roundly criticized by reviewers and fans alike.
Even though Patrick Stewart doesn't want to be Picard anymore, he doesn't regret his role in the slightest. In William Shatner's ST documentary The Captains, he want so far as to say that he is perfectly happy if he were to be remembered mainly for having played Picard after his death.
Most of the other cast members hold a similar fondness for the show, and don't mind a little typecasting if only because they're touched by the love of the fans and are proud of the best moments of the shows.
The only one with real regrets about his time on TNG is Wil Wheaton: a large portion of his autobiography Just a Geek focuses on his coming to terms with his (in retrospect) ill-made decision to leave the show due to Fan Backlash and increasingly being sidelined by the show's creators. It probably didn't help that his character was one of the most hated on the show, either. Nowadays, he seems to look back on his time on TNG with real nostalgia, and doesn't seem above some good-natured ribbing of his old character, either.
Marina Sirtis felt that the worst of the Trek movies was Nemesis, saying that she fell asleep during its premiere. She also mentioned wanting to slug the director, Stuart Baird. This made it into the DVD featurette. (They were really hard up for sound bites.)
If so Richard Dean Anderson: before he was Jack O'Neill Stargate SG-1 he was everyone's favorite mullet-sporting hero, MacGyver. Now, while Anderson has always been deeply appreciative of the show (going so far as to appear on the SNL spoofMacGruber and doing a well received Super Bowl ad for Visa as the character) he's been noted as having been greatly stressed out by it since he was the star of the show and thus he never could take a break. It was one of the reasons he stated that SG-1 had to be an ensemble show, so that he wouldn't have to "carry" it by himself.
Amy Jo Johnson, the original Pink Ranger of Power Rangers, has shown everything from visible discomfort to outright shame in regards to the role that made her famous (and probably typecast her forever). This has affected many of her fellow actors, but most of them were martial artists first and foremost and didn't have as great of a desire to establish a serious acting career as Johnson did. Many of them have commented that they'd love to come back for cameo roles every year if asked, and look back fondly at their years on the show.
What makes this ironic is that Johnson shamelessly shilled the Mighty Morphin' Power Rangers: The Movie movie in 1995, going so far as to suggest it was as good as Star Wars and The Wizard of Oz combined (a comparison for which she was roundly mocked). In retrospect, it's hard not to wonder if she had been paid to give that statement, or if she had somehow been forced into making it.
For years, David Yost (who played Billy Cranston, the original Blue Ranger) seemed this way, but in a 2009 interview he admitted that the main issue was his getting gay-bashed behind the scenes, and that he didn't hate the show itself or the fans, who have been very supportive.
If Amy Jo is the best example of this from Power Rangers,Lost Galaxy's Danny Slavin is a very close second. It's believed that he only took the job to pay for law school, and has repeatedly turned down invitations to Power Morphicon. Not helping matters, reportedly the producers screwed Trakeena's actress out of most of her paycheck during the Lost Galaxy/Lightspeed Rescue crossover episode, which led to him walking off the set in protest. It took a miracle (and the producers calling in personal favors) for him to cameo in the 10th anniversary episode "Forever Red".
Both Johnson and Slavin do seem to have softened up a little bit in recent years, though. Johnson, now that she's carved out a respectable career in acting and music, has slowly started to ease back into the fanbase, doing an interview with one fansite and mentioning encounters with Ranger fans positively (although between a phobia of large crowds and past issues with stalkers, don't expect to see her at conventions any time soon.) Slavin, on the other hand, is still almost a total recluse regarding Lost Galaxy; however, he was one of the handful of Rangers who has returned for the 20th anniversary special.◊ Of course, he might have less than noble reasons for that, but it's a start.
In November, 2014, Johnson, in response to a challenge by Yost to do it if she raised enough money in her Indiegogo campaign for a film, played guitar and sang in her original costume on the corner of Yonge and Dundas in Toronto (possibly the busiest intersection in the country). She admitted she was nervous but apparently had a great deal of fun doing it and was warmly received and applauded for it.
In an interview, the widow of Ray Goulding (of Bob & Ray) noted he didn't like to have the early episodes of the duo's 1951-53 TV show brought up in later years because "it was infancy for television" and he was "appalled at how really naive they were about what to wear and how to appear." Different times...
Tom Baker was reportedly keen to distance himself from Doctor Who after leaving the show, refusing to appear in the 20th anniversary episode "The Five Doctors", and for a long time refusing to do conventions and public appearances related to the show. This was at least partly due to the length of time he spent on the show and being quite burnt out about it and partly because his iconic performance largely overshadowed everything else he did since then. It's worth noting that by 1980, sources show Baker as alcoholic, despondent, and nearly impossible to work with; executive meddling and heavy typecasting had taken a toll, his marriage was on the rocks, and he was not at all enamoured of newer writers like Christoper Bidmead or producer John-Nathan Turner. He was nearly 50, and had little career left. He seems a lot more comfortable being associated with the show in recent years, however. In 1993, Baker filmed a small part for the short "episode" "Dimensions in Time". It's said there was far more planned using a different script, but Executive Meddling and a primadonna host got in the way. From 2009, Baker returned as the Doctor for three five-part series of audio dramas for BBC Audio, and in 2011, he finally began to star in the audio dramas for Big Finish Productions. He has shown some regret about not doing "The Five Doctors" and distancing himself from the series at large, but at over 80 years old his health will not allow more involvement with the exception of a brief cameo towards the end of the 50th Anniversary special.
It took a long time for Peter Davison to become comfortable with his tenure as the Doctor. With most of his career still ahead of him, he had been terrified of being typecast and did everything possible to prevent it, including insulting the show to the press. In recent years, Davison has also mentioned the show's low budget and poor treatment from the BBC were a major source of his resentment towards the franchise. He has since said that he wishes that he could have worked on the show when it had the budget, studio support, and prestige it enjoyed under the leadership of head writers Russell T Davies and Steven Moffat. From the late '90s onwards, he's happily been playing the Doctor in monthly Big Finish Doctor Who episodes, and in 2007, reprised his role on TV in the mini-episode "Time Crash" as part of a charity drive. David Tennant used the short as a massive fan-gasm shout-out to Davison's tenure on the show: "you were MY Doctor." Tennant has repeatedly cited Davison's interpretation of the Doctor as his primary inspiration, and reason for becoming an actor. Davison had always felt that he was too young for the role. In "Time Crash" he felt he was at a more fitting age to play the Doctor, and had a grasp on the character that he was happy with. Ironically, the role of the Doctor being played by a younger man (and the contrast between the character's physical age and his actual age) was one of the primary things that carried over into Tennant and Matt Smith's portrayals, thanks in part to Davison's example.
The Second Doctor Patrick Troughton quit the show in 1969 to avoid being typecast, and because he wished to return to other programs. He went as far as to urge Frazer Hines (Jamie McCrimmon) and Wendy Padbury (Zoe) to depart at the same time. Troughton enjoyed making comebacks in "The Three Doctors" and "The Five Doctors", and finally alongside Colin Baker in "The Two Doctors", and looked like he was thoroughly enjoying himself in all of them. Of course Troughton didn't hate the character — he would make himself available at conventions, and any time he and Jon Pertwee were at the same convention, the two would appear at joint panels and jokingly mock-bicker as Two and Three did in "The Three Doctors" and "The Five Doctors". Troughton also counseled Davison to stay on only 3 years, and this aided in his decision to leave the show in 1984.
Janet Fielding has stated that she was pretty bitter towards the show when she left because she wasn't happy with how she and her fellow companions were treated. This reached its highpoint with a notorious on-stage outburst at Panopticon 1993 when she told a room full of fans that any show that treated its female characters as badly as Doctor Who did deserved to have been cancelled. She's since gotten over it and is much more comfortable with the show now, although her negative remarks about certain stories on DVD commentaries have still caused controversy.
Surprisingly subverted by Colin Baker, who you would think — given that he was the only actor playing the Doctor to be fired from the role, that his era was for a long time not incredibly popular with fans and that, well, he had to wearThat Coat — would have plenty of reason to not want to have anything to do with the show again. Instead, barring some rather understandable regrets, he's always appeared quite enthusiastic about the show, being associated with the show and returning to it in some form on occasion. Baker, long before David Tennant took the trope and ran with it, was theAscended Fanboy on Doctor Who, having been a childhood fan of the show. He too has been doing Big Finish dramas as the Doctor continuously since the late 90s, and he (and the writers) went the extra mile to completely rehabilitate Six's reputation, leading to him being a poster boy for Rescued from the Scrappy Heap.
Christopher Eccleston left after Series One, due to having spats with the executives over "the way things were being run" and, according to him, people being bullied by directors on-set was common. He (politely and after a few cordial meetings with Moffat) declined to return in person for the 50th anniversary - which could have had to do with his commitment to Thor: The Dark World.
Legendary Development Hell episode "Shada", written by Douglas Adams, was originally rushed out by him in four days when his previous script got rejected thanks to Executive Meddling. Some of the script was shot, but then shooting was interrupted with a strike, causing it to be cancelled. Adams, for his part, was happy about this, because he thought "Shada" was not up to much - however, since people love Douglas Adams' writing, fan demand became huge. In 1992, he accidentally signed away rights for the BBC to make a direct-to-video version of it with linking narration by Tom Baker, and was so distressed by this that he declared he would give away every penny of the proceeds he made of it to charity as penance. People who have seen the script say that while it wasn't anywhere near as godawful as the notably perfectionistic Adams thought it was (notably, it contains one of the all-time-brilliant Douglas Adams characters, Professor Chronotis), and gives the Fourth Doctor some of the wittiest, most enjoyable dialogue he was ever given), it is not up to the standard of his usual work, having gaping plotholes, minor characters who never get to come into the limelight, a very boring villain and being mostly a lazy, watered-down, low-budget retread of his previous Who script "City of Death". Both the Big Finish version (which was forced to shoehorn the Eighth Doctor into the role as Tom Baker refused to do radio scripts at the time) and the 2012 novelization by Gareth Brooks (written after his death as Douglas Adams would not allow anyone else to novelize it) were both attempts to fix the problems that Adams himself had identified - not to mention Adams' own Ascended Fanfic of the story, Dirk Gently's Holistic Detective Agency, which replaces the Doctor, Chris and Claire with Expies and rescues Professor Chronotis from oblivion.
Robin Williams did not like being called "Mork", or being greeted with "Nanu nanu". Even as far back as "Reality, What a Concept..." (1979) he had to let the crowd (chanting "Mork! Mork! Mork!") know that he preferred doing stand-up. On his "Live 2002" album, something similar happened, and he actually said he'd rather forget Mork. Most notably, for years he'd been unwilling to say "Nanu nanu" even as a reference... until recently, it seems (at around 2:18). Perhaps he had mellowed.
Actor and singer Danny Smith is rumored to be annoyed at people who still think of him as Merton Dingle from Big Wolf on Campus. It's unknown whether it's true or if he's over it.
Morgan Freeman does not want to be remembered for being Easy Reader, and has made as much clear when interviewers try to ask him about it. He's mellowing a little bit about it, but still feels that he stayed with The Electric Company for too long.
Tina Louise was NEVER Ginger on Gilligan's Island. Don't ask her about it, she won't talk about it anyway.
To the extent that she refused to reprise the role even for the Filmation cartoons (in one of them Dawn Wells voiced both Mary Ann and Ginger).
Ellison also wrote a book ranting about how Executive Meddling ruined his original script for Star Trek episode "The City on the Edge of Forever".
While he doesn't necessarily dislike I Have No Mouth and I Must Scream he a bit upset that people keep talking about it, rather than his other works, as he wrote it in a day and doesn't consider it his best work.
Likewise Shigeki Hosokawa, who played the title character in Kamen Rider Hibiki, made a blog post just after the show ended in which he talked about how badly the second half of the show was mismanaged, in particular complaining about how they got rewrites for the final episode while filming it. Like Odagiri he apparently dodges the subject of Hibiki in interviews, and though in that same blog post he said he'd be glad to come back (if someone competent were in charge), he's practically the only main cast member who didn't return in Decade. (In Decade, the past Rider series casts are usually Alternate Universe versions that are only loosely based on the original casts. Hibiki shares with Den-O the distinction of having its original cast reassembled... minus Hibiki himself and his apprentice Asumu. It's hard to know if they were recast because Hosokawa declined to return, or if they just didn't want the whole "Hibiki turns into a monster and Asumu has to Shoot the Dog and become the new Hibiki" thing to happen with the originals.)
Tamao Satou, the actress of Oh Pink in Chouriki Sentai Ohranger, had shown dislike for the role since the season ended. It took time, but she's apparently had a change of heart since then, taking part in a photo shoot for the theater premiere of one of the recent Sentai VS Movies in-uniform, and most recently performed a cameo role of the character alongside Oh Red actor Masaru Shishido amongst other Sentai alumnists in the 35th anniversary series Kaizoku Sentai Gokaiger.
Masaru Nagai, who played the Red Ranger of Mirai Sentai Timeranger, now wants to be disassociated from the show and claims his professional debut was a drama he appeared in long after Timeranger. He once appeared on a variety show with fellow Red Ranger actor Tori Matsuzaka (Takeru Shiba in Samurai Sentai Shinkenger), who reportedly made thinly-veiled comments about actors trying to deny that they starred in tokusatsu. Unlike the above case, he refused to return for Gokaiger, letting Yellow Ranger Shuhei Izumi do it instead.
Tetsuji Tamayama played the Breakout Character of Gao Silver in Hyakujuu Sentai Gaoranger and has since gone on to a very successful TV/film career. Despite speaking positively about Gaoranger, he's declined to reunite with the cast or discuss the show in interviews - allegedly because his management requests that journalists not ask him about it.
Most of the adults of Full House did not like the show and hated its Tastes Like Diabetes nature, with Bob Saget and John Stamos being the most vocal (Dave Coulier appears to be the only adult male lead who has expressed no regret over his role). Unusual for this trope, the entire cast got along extremely well and remain close friends to this day. Stamos has mentioned on talk shows about having a psuedo-Revival where him, Saget and Coulier would be roommates after the kids had grown up and left. Saget has joked about an event where him and Stamos were near a car accident, and speculated on what the driver must have thought when they saw "Danny and Uncle Jesse" coming to the rescue.
John Moschitta Jr. dislikes being known for his fast-talking Micro Machines commercials, and has called Micro Machines "some of the lamest toys" in interviews.
It was rumored around the fandom of Lexx that Michael McMannus loathed playing Kai, since the character was an actor's worst nightmare, someone who, as mandated by plot, always looks exactly the same and can't even show a facial expression. He stuck it out for the show's entire run, though.
This does seem fairly plausible because he does seem to be having a lot of fun on the few occasions that he gets to play Kai as anything other than the dead assassin.
Eva Habermann, however, was an aversion; she left the show because it took so long for news of whether or not season two was coming that she would've had to have given up other work to stay. She was under no obligation to come back for the first two episodes, and did it just to give them time to work The Nth Doctor into the plot instead of forcing the writers to just drop it on the audience out of nowhere.
"Weird Al" Yankovic hates most of The Weird Al Show because of all of the Executive Meddling behind it, with the execs trying to make it more of a Educational Shownote Due to then-new rules about the amount of educational content on kid's tv while Al wanted more of a Pee Wees Play House-like show.
Although he doesn't outright hate it like most examples of this trope, John Cleese has stated he always had a mixed reaction to Fawlty Towers most famous episode The Germans because of all the Memetic Mutation surrounding the episode and the loss of its original meaning.
Cleese even expressed irritation about most of the sketches of Monty Python's Flying Circus, feeling they were repeating themselves very quickly on. He also felt that the TV format didn't allow them to perfect the sketches as well as he wanted. This was also the reason why he left the series early on and want to move on to do other things. He especially dislikes one of his most well-known and popular Python sketches, the Ministry of Silly Walks, because it's so banal.
Patrick McGoohan seemed to bounce back and forth in his opinion on his creation, The Prisoner, embracing it at times (witness his participation in "The Computer Wore Menace Shoes" on The Simpsons) and refusing to talk about it at others. He reportedly declined an invitation to appear in the 2009 remake, though this was likely due to poor health (he died before it was broadcast).
He did allow himself to be quoted as saying he was pleased with the remastered DVD (and later Blu-Ray) version of the original series.
Henry Winkler hated being remembered only as Fonzie, and refused to answer to fans who called him that. However, some references in Arrested Development suggest he's mellowed over time.
Robert Reed absolutely hatedThe Brady Bunch (but not the Brady Bunch - he loved the kids), feuding with creator Sherwood Schwartz throughout the run, trying to get out of his contract and flat-out refusing to appear in the final episode because the script was so bad (had the show been renewed for a sixth season, Schwartz would have seen to it that the family would be without Mike Brady). However, he returned for the later TV movies and series (and the TV movie adaptation of Barry Williams' memoir Growing Up Brady is dedicated to Reed's memory).
Paul Schneider of Parks and Recreation. It's hard to blame him considering how undercooked a character Mark was, and then later was pretty much the odd man out when the series found its identity in season 2 that ended in his exit, but Schneider has been honest in his bitter feelings about his experience on the show and that it left him with a pretty sour outlook on mainstream acting as a whole (he now selects low-key role in independent projects and takes a lot of time off in-between jobs). When the creators kept the door open for a return, he expressed an explicit disinterest in ever reappearing again, which may explain why Mark has slid into Un-Person territory in later seasons.
Ashley Pharaoh, co-creator of the much-derided Bonekickers, penned a "letter to my younger self" article containing sage nuggets of advice... one of which was "Do not write Bonekickers".
Mandy Patinkin has gone on record as saying that starring in the first two seasons of Criminal Minds was the worst mistake of his acting career, despite the praise critics heaped on him for his performance, since he personally considered the show's content too disturbing for network TV, in particular the show's heavy ratio of female victims who were raped and/or murdered.
The creators of Friends openly acknowledge in one of the Season Eight commentaries that they don't like the Chandler/Monica plot in "The One With The Truth About London."
They also have some disdain for Season Six, feeling they were simply going through the motions during that time period. Not surprising, given that this was when a lot of the backstage drama with issues like Matthew Perry's drug addictions really began to hinder the series.
The one episode almost everyone involved with the show seems to dislike the most is "The One With The Cat" due to the ridiculous plot about Phoebe being convinced that her dead mother was reincarnated in the form of a catnote The two big problems were A) it came just after Phoebe finally met her real birth mother and B) Phoebe not only made out Ross to be the bad guy in wanting her to return the cat to her rightful child owner, the rest of the gang agreed with Phoebe, forcing Ross to apologize for somehow not being a supportive friend.. The cast and writers all thought it was a terrible idea, but since co-creator Martha Kauffman was pushing strongly for the episode to get made due to the death of her own mother, they were all reluctant to openly voice their objections to the script.
Spitting Image: Co-creator Peter Fluck has gone so far to claim he "hates puppets" in an interview with The Guardian. Back in 2000 he planned to throw all the 900 and counting puppets of the original show on a bonfire because he was so sick of them. Luckily someone got a better idea and decided to simply auction them.
Initially, James Gurney gave his blessing to the Hallmark miniseries of Dinotopia, but he was very unhappy with the final product. He had wanted an original story, preferring to leave the characters from the original books in everyone's mind, but he didn't like where they took that original story.
Ted Knight did not like being remembered as The Ditz Ted Baxter from The Mary Tyler Moore Show, and it caused him a lot of personal angst. The role's The Danza aspect was responsible for a lot of people confusing actor and character.
Josette Simon came to strongly regret playing Dayna in Blake's 7, as she felt that the producers took advantage of her youthful naivety and lack of confidence to get her to play a "hot exotic warrior woman" part that she viewed with hindsight as both sexually and racially demeaning.
Sally Field absolutely disliked working on The Flying Nun, though she has nothing against the show's fans.
Robert Lindsay and Zoë Wanamaker were both openly negative about My Family even while it was on the air, claiming at one point that they had refused to film an episode because the script was so bad. Right up until the show was finally cancelled in 2011 they continued to state in interviews that they felt there was little of quality in it.
The cast and crew all seem to have had this reaction to season 4 due to it being widely seen as a drop in quality from the previous seasons. They even lampshade this within the show in season 5, where the events of season 4 are referred to as "the gas-leak year".
A milder example from Stephen Amell in Arrow. While he speaks very highly of the show and cast, he's not pleased that Susanna Thompson (Moira Queen) and Paul Blackthorne (Quentin Lance) got virtually no publicity in the advertising/marketing for the second season, feeling that the promotion didn't do them justice. He similarly criticized WB for announcing plans for a Flash film and a new actor the day after The Flash posted strong second-week ratings, showing true staying power, feeling it undercut both the show and Grant Gustin..
Art James, host of Blank Check, said that he and the staff hated the show, and would sometimes call it "Blank Mind" because it required so little skill from the contestants.
Gene Rayburn did not recall hosting the 1985-86 Break The Bank as a happy experience. Him being replaced by Joe Farago in the next season didn't help matters either. Thus we'd never again see any reruns of Rayburn Bank (less so since GSN hasn't shown that particular series).
The embargo of the Rayburn episodes goes all the way back to 1986, when CBN Cable Network only showed the Joe Farago episodes.
Rayburn was infuriated when Rolling Stone magazine revealed his real age in an article, claiming that the information would probably get him fired due to insurance problems. And he was right: shortly after the article appeared, he was fired. Making it even worse was that despite the format being silly and calling for a silly host (with Gene known for being a total goofball on Match Game), Kline & Friends insisted on telling him not to be silly because Break the Bank was supposed to be a serious and suspenseful show.
A possible related Rayburn-embargo is the case of The Match Game-Hollywood Squares Hour. Rayburn wasn't happy on the show, partially due to the inexperienced Jon Bauman but in large part because the Squares format was so broken; Gene Wood reportedly said that Rayburn was "dragged kicking and screaming" into the show. But this is as likely (or less so) as it just being chalked up to a dual-ownership issue, as Fremantle Media and MGM have the rights to the respective shows now.
Chuck Henry will not allow his 1989 version of Now You See It to be seen in reruns, fearing that his credibility as a newscaster would be hurt if people remembered that he was a game show host at one point — consensus is, however, that Henry was a competent host (and besides, what more damage could it do after having to be rescued while reporting on a forest fire?). GSN does air the original Jack Narz version occasionally.
Game Show host Tom Kennedy had this happen a couple times through his career. While he enjoyed doing a nighttime version of The Price Is Right in 1985-86 (stating that he would've continued with it had it been renewed), he felt he didn't do a good job (like Henry, fans disagree greatly). Unlike Chuck Henry, though, he let GSN air his version.
Speaking of The Price Is Right... shortly after Drew Carey took over for Bob Barker, Drew began involving then-announcer Rich Fields in a series of "humorous" skits during the Showcase rounds. These skits, which gained the Fan Nickname "Drewcases", were widely derided by the fanbase as unfunny and demeaning. Drew apparently got the message, as he quickly phased them out and admitted that they didn't work.
Peter Tomarken, best known for hosting Press Your Luck, later did a home shopping/game show hybrid called Bargain Hunters, which he is reported to have called "a piece of shit".
Richard Bacon, host of the short-lived British quiz show 19 Keys, would later say of the show, "It was a game show that was almost impossible to follow, let alone enjoy. Buzzers, sirens, a prize fund that would go up or down for no apparent reason - imagine being in a pile-up on the M25 with me in the car screaming general knowledge questions at you. That was 19 Keys."
Wheel of Fortune host Pat Sajak has made it abundantly clear that he hated the show's short-lived "Megaword" category, used only for a few months in late 1994-early 1995 (the puzzle was a large singular word that, after solving, a contestant could use in a sentence for a cash bonus). He would snark about the category literally every time it came up, and when a contestant mentioned it in a 2014 episode, Pat remarked that he "hated every moment" of the category.
An in-universe example: in Extras, Andy Millman (Ricky Gervais) finally achieves his dream of writing and starring in his own sitcom, only to see Executive Meddling and Fan Dumb turn the whole thing into a total (though very successful) embarrassment.
Castle has an In-Universe example when the title character, a novelist, got bored with his current hero (Detective Derrick Storm) and Dropped a Bridge on Him at the end of his last book. He then starts up a new series about Detective Nikki Heat, based on Beckett.
In a later episode, the actress who plays Beckett's favourite character on her favourite science fiction TV show gets interviewed as part of a murder inquiry, and makes no secret of how much she hated playing said character on said show. Beckett looks like a puppy who's been dropkicked. The actress later turned out to be the murderer, and killed the victim to prevent a revival of the series.
