History ReplacementScrappy / GameShow

* For Season 2 of ''Series/BeatTheGeeks'', Blaine Capatch replaced J. Keith van Straaten whom Creator/ComedyCentral thought wasn't geeky enough. Capatch drew hatred for being too [[LargeHam hammy]] and needlessly condescending to the contestants. At least once a show. he'd scream "GET OUT!" to eliminated players.

Capatch drew hatred for being too [[LargeHam hammy]] and needlessly condescending to the contestants, to the point where he'd scream "GET OUT!" to eliminated players at least once a show.

** When the show returned from a three-year hiatus in 1991, original host Creator/DickClark was busy with ''Series/TheChallengers'', so John Davidson took over there as well. As on ''Squares'', Davidson frequently tripped over the rules (many episodes have the offstage staff shouting at him when he messed up) and rarely felt as if he were in control.
** {{Downplayed|Trope}} with Donny Osmond, who hosted the 2002-04 incarnation. While certainly no Dick Clark, and mildly derided for his over-exuberance (e.g., constantly [[NoIndoorVoice screaming "OH! OH! OH! OH!"]] when someone failed to clear the [[BonusRound Winner's Circle]]), his imperfections as a host were overshadowed by the [[TheyChangedItNowItSucks many, many changes to the gameplay format]] relative to the prior versions.

** Towards the end of Season 12 in 1995, Harry Friedman replaced Nancy Jones as producer. While the show's updates were consistent under Jones' tenure, Friedman made a myriad of changes starting in Season 14 until his retirement after Season 37. Among his "contributions" were a single wheel template in use since 1996 (prior to this, each round used a separate template; this caused wedges such as $750 and any $1000+ value to be retired), an electronic puzzle board in 1997 (probably his most justifiable change due to taking less production time than the trilon board, though this essentially rendered Vanna White TheArtifact), the phasing out of returning champions in the late 90s (while keeping them on ''Jeopardy!'' and eventually abolishing the limit in 2003), Toss-Up puzzles and the retirement of Creator/MervGriffin's music packages in 2000 including "Changing Keys", Prize Puzzles in 2003, and a $1,000,000 cash prize in 2008. In 2013, it was confirmed that he approved every puzzle that makes it onto the show, leading to no small amount of derision for a decline in puzzle writing. What makes this case especially damning is that Friedman did a much better job producing sister show ''Series/{{Jeopardy}}'', implying that he never cared about ''Wheel'' to begin with. Even more damning is that, despite all this, he managed to last ''twenty-five'' years on the show. Just before his 2020 retirement, Friedman was asked about the lack of same sex couples on ''Wheel''. He answered that the show wasn't ready for it and that the staff must "take very measured steps" for it to happen. It speaks volumes that the ''very first'' couples week after Friedman's departure featured a same sex couple. The show's ban on same sex couples under Friedman was later confirmed by a gay contestant who was told that he and his husband were not allowed to audition together. Friedman retired at the end of Season 37 to the joy of fans, and Mike Richards was announced as his replacement; up to his 2021 firing, Richards averted this with more modern puzzles, bringing back the "Changing Keys" theme and the ''Celebrity Wheel'' primetime specials drawing high ratings, as well as promising a tournament for Season 39.

** Beyond a large number of unnecessary cosmetic changes and rules changes that cheapened the game, the main point of contention for the 1990-1991 revival was the hosting style of Patrick Wayne (Creator/JohnWayne's son). Wayne often came across as fake in the interviews and read the questions and RulesSpiel in a monotone, but would [[SuddenlyShouting scream]] "YOU WIN!" if a contestant won the game, or "YOU BLOCK!" if a contestant successfully blocked his/her opponent. His hosting style gained MemeticMutation in the game show community for being one of the worst hosts out there. Not helping matters was a "Divorced Couples" week, which had divorcees competing against each other for money; the week's final episode saw Wayne classlessly stating to all of them that "divorced couples can still have fun together, riiiiiiight?"

* Many long-time watchers of ''Series/ThePriceIsRight'' were wondering "What were they thinking?" when the show decided to replace the retiring Creator/BobBarker with Creator/DrewCarey as host. In Carey's defense, it would be hard for audiences to see ''anyone'' replacing Barker, since he had hosted the show for [[LongRunners an amazing 35 years]]. Those who hate Drew criticize him for trying to inject humor at inappropriate times (most notoriously, his decision to incorporate TheAnnouncer into "comedic" showcases that generally elicited negative reactions from the fanbase; to be fair, [[OldShame Drew got the message]]), fluctuating enthusiasm (he seems to act more placid when contestants are performing poorly), and [[MotorMouth talking way too fast]]. Some longtime watchers also applied this to Tom Kennedy and Doug Davidson, who hosted various syndicated versions in the 1980s and 1990s, if only simply because they weren't Bob Barker. Criticism of Carey has declined over the years, especially as he began toning down the forced humor and hosting more professionally.
** This can also apply to the announcer's booth. After Johnny Olson's 1985 death, Rod Roddy's 2003 death, and Rich Fields' 2010 departure, the show tried out various guest announcers on-air before determining the successor. The substitutes (with the possible exception of Randy West) are all victims of Replacement Scrappydom to some extent, but some of the more prominent ones include:

** Bart Eskander, the show's director from 2000-2009 (and the show's third after Marc Breslow and Creator/PaulAlter), was hated by most of the fanbase for his oversimplified and stiff style. It’s a good wonder he lasted about nine years, especially since he served as assistant director to both Breslow and Alter for many years.
** Mike Richards (the show’s executive producer from 2009-2019) got flak for replacing Roger Dobkowitz as series producer in Season 37 due to Creator/FremantleMedia's decision to put the show in a new direction, and replacing Syd Vinnedge as Executive Producer the following season. Bart Eskander's replacement, Rich [=DiPirro=], once went so far as to tell him he was ruining this show. Some people even celebrated Richards' departure for Creator/{{Sony|PicturesTelevision}} in 2019.

* When ''Series/CardSharks'' was revived in 1986-89, it took two forms: a Creator/{{CBS}} version with Bob Eubanks hosting, and a syndicated version with Bill Rafferty, both of whom had markedly different styles from original host Jim Perry. While Rafferty averted this, Eubanks was seen as either a straight example or another aversion: some fans felt that his sleazy demeanor that he had codified on ''Series/TheNewlywedGame'' didn't fit ''Card Sharks'' at all, but others felt that he made it work.

* The illness and later death of Allen Ludden prompted ''[[Series/{{Password}} Password Plus]]'' to attain a new permanent host in Tom Kennedy, who kept the show going another 2 years. A subsequent revival, ''Super Password'', had Bert Convy as the host; some fans consider him a replacement Scrappy due to his chatty nature and frequent bloopers, but ''Super'' lasted five years under his tenure.

** After Trebek's death, the remainder of the infamous thirty-seventh season was carried by sixteen different guest hosts, each of whom had varying reception. However, one guest host, [[Series/TheDoctorOzShow Dr. Mehmet Oz]], was universally panned by fans and former contestants due to his extremely controversial reputation. Even without his reputation, his hosting was considered mediocre; at least one contestant who played on an Oz episode said that Oz screwed up several clues, as well as making fun of her behind the scenes.

** [[Series/SixtyMinutes Bill Whitaker]], another guest host, has also received flak from fans due to his dull, monotone delivery. Not helping is that his first episode took two hours to tape according to the production staff and some contestants.

** In a bizarre reversal of the fans' general opinion on Harry Friedman, Mike Richards, who replaced the retiring Friedman as executive producer in Season 37 and (as stated above) was already divisive during his tenure on ''Price''. While Richards was commended for his work on ''Wheel'', his job on ''Jeopardy!'' was a completely different story. He was criticized for approving some of the show's most controversial clues (including penalizing "Barry Gordy" in a clue that asked for "Berry Gordy" although both sound '''exactly the same''' in most dialects), as well as attempting gimmicks such as adding teams (a concept previously in the All-Star Games back in Season 35, but ended up a failure among both audiences and staffers, including then-host Alex Trebek) to the College Championship (said concept was scrapped once Davies replaced Richards weeks into Season 38), and infamously stating in an interview that Oz was [[BlatantLies neither divisive nor political]]. And then he himself became subject to controversy in August 2021 when he was reported to have been in "advanced negotiations" to become Trebek's permanent successor. This alone was met with near-universal backlash, especially given allegations of age and sex discrimination towards staffers on both ''Jeopardy!'' and ''Price''. Fans applauded his decision to stop hosting after one week of the next season was taped, and they were also relieved to see him getting fired from the show and replaced by Davies (himself considered [[MorePopularReplacement a much better showrunner]] than Richards) by month's end.

* Mayim Bialik is currently one of two hosts of the show, but she's seen as this to both Trebek and also Ken Jennings, the other host, with fans constantly asking when Ken will be back in YouTube comments of her episodes.
