Archive Panic: The RPM finale marked a solid 700 episodes, and with two new seasons already out, and a third season going on currently, the episode count is over 800 episodes. It would take someone quite a while to watch all the episodes. Luckily, every season (minus the movies) is available on DVD or Netflix for binge-watching. Cut the openings and closings from your watch time, and it'll be significantly easier.
Primarily over which seasons are the best/good/bad/crap.
Saban's decision to start skipping Sentai series - Tokumei Sentai Go-Busters became the first series to be intentionally skipped in favor of adapting Zyuden Sentai Kyoryugernote the fact that Saban did this immediately after having to adapt both Tensou Sentai Goseiger as well as Kaizoku Sentai Gokaiger in Megaforce due to contractual obligations. Many fans expected Saban to skip Goseiger and adapt Gokaiger, the 35th Sentai series and the one that is a Milestone Celebration for that franchise, for the 20th PR series, on top of the former being seen as an extremely dull Sentai. Generally, camps can be split into 2 groups: people who are glad that Xnote Go-Busters/Ressha Sentai ToQger is being skipped while Ynote Kyoryuger/Shuriken Sentai Ninninger is being adapted, and people who are irritated that Y is being adapted while X isn't. Although with Gobusters being adapted into Power Rangers: Beast Morphers showing that Saban-er, Hasbro is not opposed to adapting sentai out of order, this may become a moot point.
Turbo (the first half, anyway) and Bruce Kalish's run on the show, Mystic Force through Jungle Fury (though he worked on SPD as well), tend to be considered this (although each season bar Overdrive has a notable fanbase, and nowadays Mystic Force and Jungle Fury are Vindicated by History). Also a specific period during season 2 of Mighty Morphin after Jason, Zack and Trini's actors left the show, before their characters leave ("Power Transfer II"), because their characters were in the show but only using stock footage and while morphed using bad dubbers for their dialogue.
The Neo-Saban Era is largely seen as this. Of the four entries produced in this Era, the only one unanimously considered good is Dino Charge. Samurai however was largely disliked upon its initial run,note Enough to cause previous seasons to be Vindicated by History though it would later receive this itselfMegaforce was openly hated for failing as an Anniversary Season, and Ninja Steel was considered a major step down after Dino Charge, and So Okay, It's Average at best.
Evil Is Sexy: Played with in the earlier seasons, but it wasn't until In Space's Astronema that it took complete hold. Now every season there is at least one attractive humanoid evil female who most of the time fights the good guys.
Fanon: Due to every Power Rangers series other than RPM and Dino Charge being in the same universe and the fact that many elements or other occurrences in the show aren't officially explained, this happens a lot. There's even more when one considers things that were once going to be official explanations, but were later taken out for one reason or another, such as the Lightspeed Aquabase being built from old destroyed Zords, Billy having developed the Turbo morphers during Zeo and the Great Offscreen War three thousand years ago mentioned in Lost Galaxy and Wild Force being the same event, indicating that the Galactabeasts and the Wildzords are connected.
Mighty Morphin' was an instant hit, and became a major phenomenon, on par with Teenage Mutant Ninja Turtles a few years earlier and Pokémon a few years later. The sequel series couldn't possibly keep up that momentum, and Mighty Morphin' is far and away the best remembered installment, and the one that the average person is referring to when they say simply Power Rangers.
Within Bruce Kalish's run, SPD is pretty much the only series that has a sizable contingent of fans. After all, it boasts some of the better acting of the series, a large amount of Character Development, and Bridge Carson, one of the most eccentric characters to ever put on a Ranger uniform.
Subverted in regards to the Neo-Saban era, where the first entry, Samurai, was a top contender for the worst entry in the franchise for a while - and while Megaforce is now seen as worse, Samurai is still a Contested Sequel at best. In the case of the Neo-Saban era, it's third installment wins, since Dino Charge is considered the best.
With fans of tokusatsu shows. While people might debate about the quality of the adaptions, a solid chunk of the western Super Sentai and Kamen Rider fans are still friendly with Power Rangers fanbase due to it being a huge gateway into the wider genre of tokusatsu, the only adaption that they really hate being Masked Rider.
Also with the Devil May Cry community thanks to the large number of actors who've worked for both franchises, especially Johnny Yong Bosch, Reuben Langdon and Dan Southworth.
Girl-Show Ghetto: In the toylines, the female Rangers usually get basic action figures produced and that's it, while the boys get Environment-Specific Action Figure variations out the wazoo. With the Jungle Fury and RPM toys, Bandai America has actually created extra marketable (read: male) Rangers for the toyline to give these extras to, rather than give them to the existing female Rangers. Then again, that's less misogyny and more because girls don't sell: young boys really are the primary consumers of action figures for fighting series, and in second and third grade, owning a Pink Ranger "doll" can be hazardous to your health. Some series have made non-Yellow females a Blue or White Ranger rather than Pink, so that even if little boys don't want her action figure (because the costume will usually have a skirt on it) they can still be persuaded to buy other merchandise based on the character - her weapons, mecha, etc. Averted in the '90s. Kimberly was (and is) one of the most popular Rangers, Pink or otherwise. The Pink and Yellow Rangers were included in plenty of the merchandise, including children's clothing and the McDonald's Happy Meal toys— something that would never happen today. There was even merchandise targeted directly to girls, such as Kimberly and Trini/Aisha Barbie dolls.
Growing the Beard: Starting with Power Rangers in Space, the stories grew much more well-developed.
Reportedly Disney was embarrassed to own the franchise (they only got it because it came with the package of the Family Channel that Disney acquired from Haim Saban) because it didn't really fit with them and then almost immediately after they sold the series back to Saban they ended up purchasing Marvel in order to tap into the boy market.
When Saban bought the franchise back from Disney, he was able to get them to cut the price by claiming he would take the show to The Hub, which anyone who actually knew anything would know couldn't happen at the time, due to the block being co-owned by Hasbro, while Power Rangers toys were made by Bandai. Fast-forward to 2018, and Saban opts not to renew their partnership with Bandai of America, instead partnering with Hasbro.
Even funnier when you realize that Bandai of Japan's rival is TakaraTomy, which co-produces Transformers with Hasbro.
And then Saban sold the entirety of the franchise to Hasbro, while staying on as a creative consultant for future seasons for the time being. Interestingly, this is much like Disney buying Lucasfilm from George Lucas, who, after producing several divisive Star Wars films with the prequel trilogy, wanted to sell the franchise to a company so he'd stop receiving as much flak for them. Saban might have felt similarly, as the Neo Saban Era has had more misses than hits (with the only season most can agree is good is Dino Charge), and recently falsely copyright claiming Power Rangers reviews on YouTube most likely to keep any bad criticisms from being heard by blocking them about a week before the announcement of the sale.
It's the Same, Now It Sucks!: A common complaint about the Neo Saban era was that with the exception of Samurai, the villains have all been aliens so farnote Megaforce is at least forgivable on the grounds that in the 2 adaptedSentai, the villains were aliens for at least some of the show; Dino Charge and Ninja Steel, on the other hand, had earth-based villains in their respective sourcematerial. Fortunately, Beast Morphers broke this trend, although only time will tell if the rest of the era will follow suitnote Toqger had Earth-based villains, but Zyuohger and Kyuranger both had aliens.
LGBT Fanbase: An argument can be made for the WHOLE franchise, starting with the dozens of attractive young men running around in rainbow spandex. One could also cite the No Hugging, No Kissing rule as playing into it; many of the friendships which are meant to be platonic are so emotionally charged that they come off as Ho Yay. Many teams have had characters that that fandom at large views as coded gay or bi (Kelsey, Vida, Jayden and Antonio, or Riley for example). It also helps that many of the ranger alumni are LGBT+ allies, and have participated in NoH8 photoshoots. With Power Rangers S.P.D. we can also point specifically to Doggie Cruger, who became an instant Bara Genre icon. His counterpart from SPD's source material, Tokusou Sentai Dekaranger, is submissive (and VERY muscular) in almost every erotic pic of him (even if it's straight!)
Macekre: While chopping up the Sentai episodes is common, season 3 of the original show really has to take the cake. In Kakuranger, the robots which would become the Shogunzords appeared first, with the proto-Ninjazords as the Mid-Season Upgrade. Saban flipped it around since there were only 5 Shogun zords and 6 Rangers. The best example: the first Monster of the Week in season 3, Vampirus, comes from episode 36 of Kakuranger. And let's not get into Zyu2 and Dairanger...
Let's put it this way: The episode 'Ninja Quest' includes American produced footage, a monster battle from Kakuranger, stock footage from Zyuranger and Dairanger, as well as footage from Zyu2. Five sources for one episode.
My Real Daddy: Judd Lynn is pretty much considered as the real daddy of PR shows, as he's the one who kept the original Power Rangers shows into favored ones, noted that there has been decline in quality after his departure in the middle of Time Force. Him being called back to help finish up RPM is also a factor why that show is a favorite. It is also worth mentioning that Judd Lynn was responsible for the second half of Turbo, which salvaged it from 'really bad' to 'at least watchable'. After Jonathan Tzachor descended into Scapegoat Creator, the news that Judd Lynn returns as the full-season director of Dino Charge is met with MUCH applause.
Narm: Various accounts, including particular acting moments and some Battlizers looking ridiculous (Just look at Lost Galaxy,Lightspeed Rescue and Dino Thunder).
Narm Charm: In general, the adult fandom doesn't so much accept the inherent cheese as eagerly snarf it down.
Padding: Most series of live on this trope. Hope you like morphing sequences! You know when an episode ran short when the full sequence plays instead of the instant, five second and/or split-screen variations.
Periphery Demographic: The show has a staggering amount of adult fans for a kids' show. This is probably because most of the current adult fans were children when it first ran.
Johnny Yong Bosch (Adam, the second Black Ranger and Green Zeo Ranger) is very well known in the anime dubbing community, especially as Vash from Trigun, Ichigo from Bleach, and Lelouch from Code Geass.
Dan Southworth (Eric, the Quantum Time Force Ranger) was an accomplished stuntman within and without Power Rangers even before getting to appear on camera. He would later do voice work and motion capture for Vergil in Devil May Cry 3: Dante's Awakening, and he also played Kenshi in Mortal Kombat: Legacy.
Sally Martin (Tori, the Blue Ninja Storm Ranger), would become a fairly well-known television actress in New Zealand after her seven year tenure in Shortland Street.
James Napier (Conner, the Red Dino Thunder Ranger), would go on to win international acclaim for directing the biopic The Dark Horse.
Scapegoat Creator: Bruce Kalish, being cited as one of the promotors of the overuse of Kalishplosions, which made the Rangers in his tenure look... weak. Along with some questionable liberties given and characterizations of the rangers on his run. While not much, he was vindicated thanks to the weak start of the Neo Saban era, and the news that due to Disney's Executive Meddling, it limited his creativity and forced him to use a lot of Kalishplosions...though that did NOT stop him from passing the Buck to Stunt-director-turned-executive-producer Koichi Sakamoto, who still to-this-day takes the ire for them from the fandom.
As pointed out by Internet reviewer Des Shinta when he reviewed Zyuden Sentai Kyoryuger and Power Rangers Dino Charge, Kalish and Sakamoto were scapegoated over Kalishplosions ONLY because no-one in the fandom bothered to check the credits of the episodes to find who the stunt coordinator was. Mark Harris, the head stunt coordinator and stunt director from SPD through RPM, was the man actually responsible for them. As noted by fans they began to pop up in episodes in Ninja Storm and Dino Thunder where he did the stuntwork, but were scantly seen due to the previous head stunt director, Makoto Yokoyama, being around. But when Yokoyama left to do the stunts for the Garo franchise in 2004/2005, Harris got the gig full time, and his poor use of explosions then flourished. Sadly, this attitude of blaming Sakamoto over Kalish however has endured because of Dino Charge, due to Dino Charge using footage from Kyoryuger which he was the head director for...only when people began citing him for Dino Charge's bad original effects and echoing-complaints about the Kalish Era's stunts, one would only need to look at the credits once again to find that Mark Harris returned to the franchise WITH Dino Charge to continue his awful stuntwork.
Jonathan Tzachor also became this after the failures of Samurai and Megaforce, which were considered eons away from the job he did in the series up until In Space (especially in the latter). In particular, as Linkara pointed out in History of Power Rangers, the cast and the staffs of Megaforce actually had ideas to make Megaforce more creative and had more development, but Tzachor shot down all those ideas for the sake of more action scenes and more following to the Sentai footages due to his personal preferences. Little wonder that he was removed for Dino Charge and replaced by Judd Lynn. It's worth noting that evidence suggests that Tzachor wanted the franchise to follow the Sentai back when he was working on it during the time before Disney bought the franchise - mainly, he was one of the people that favored having Turbo be more in line with the comedic Carranger footage, whereas Doug Sloan, the head writer, wanted the series to be more serious, as well as just how much of a Shot-for-Shot Remake of GaorangerWild Force wasnote Tzachor had flown in some of the stunt coordinators from Gaoranger, and because they couldn't speak English, there were communication issues. It's likely that the other people who worked on the series prior to his return with him were the ones who kept him in line (Doug Sloan and later Judd Lynn); much like what happened in Wild Force, not having someone to keep him in line was what led to Samurai and Megaforce turning out the way they did.
Justin Stewart was once thought to be the cause of Turbo's unpopularity as the franchise's first scrappy for being being a character with little to no flaws and the season's villains being pathetic enough for Justin to fight them off unmorphed on occasion. Justin was later Rescued from the Scrappy Heap as fans began to realize that the first half of Turbo wasn't entirely the character's fault.
Sam, SPD's Sixth Ranger, is generally considered one of the franchise biggest Scrappys. He's basically a filler character to play as the team's sixth ranger, since he was written with no character, has no character development, was used as little as possible, and was a ball of light.
Seasonal Rot: With a show as long-lived as Power Rangers, not every season's going to be good.
Turbo, Wild Force, and the seasons under Bruce Kalish (SPD through Jungle Fury) are considered the franchise's weaker entries to varying degrees.
The Nickelodeon tenure in general. While Disney's seasons were hit-or-miss, both Samurai and Megaforce have seriously underperformed. The acting is bad (note that normally people don't mind this, so it's that much worse), the plots are weak, usually just pulled straight from the Sentai, and the writers in general seem to be putting in a very minimal effort. Dino Charge however seems to have taken the necessary step in the right direction, although opinion is divided on if Dino Super Charge continued taking those steps.
Unfortunately, Ninja Steel has been seen as a step down in quality compared to the more-liked Dino Charge, due to recycling elements (like the red ranger having a missing father, the Ninja Power Stars behaving exactly like the Energems from the previous series, and some other things). It also has some problems other than those in its writing, acting, and filmmaking that are really noticeable, even if you're not looking to examine the episodes closely. Being adapted from Ninninger probably hasn't helped much, since that was one of the more less well-received Sentai seasons in the West.
Slow-Paced Beginning: Most Power Rangers series start off with filler (often Aesopof the week type episodes), but pretty much all seasons hit their stride a few episodes in, once the first major story arc occurs.
Star Trek Movie Curse: Interestingly, they had this pattern for a while. Every fifth season are the ones considered the worst: Turbo, Wild Force, Operation Overdrive, and Super Megaforcenote technically Season 21, but it and not Megaforce had the bulk of the anniversary elements. To a lesser extent, this is also true of seasons that celebrate other milestones - aside from the aforementioned Wild Forcenote the first season produced by Disney, Samurainote first season since Saban bought the franchise back also falls victim to this, although RPMnote the last season produced by Disney, and prior to Saban buying the franchise back, the last season period strangely averts this, being considered one of the best seasons in general.
Interestingly enough, due to Saban not adapting Gosei Sentai Dairangernote although the white ranger costume was adapted from that series, the core team kept the Zyuranger suits; as such, the white ranger will usually be treated as more of a seventh member of Mighty Morphin in merchandise, as opposed to having 2 separate teams for each of the two powers; Power Rangers Megaforce takes the former stance as well, listing Tommy's White Ranger powers as "Mighty Morphin White" as opposed to bundling them with the Squadron powers that Dairanger was adapted as, every 5th seriesnote this counts the Alien Rangers mini-series as a separate series with a new set of ranger suits (as in the suits are traded out completely) ends up being a good season, whereas the one before (coincidentally, it's always an anniversary series) usually is the one that bombs - In Space, Ninja Storm, Jungle Fury and Dino Charge had the 5th, 10th, 15th, and 20th set of costumesnote although had Go-Busters not been skipped at first, Dino Charge would have had the 21st set; Turbo, Wild Force, Operation Overdrive, and Megaforce, the 4 respective anniversary series, had the 4th, 9th, 14th, and 18th/19thnote Megaforce adapted 2 sets of costumes, the ones from Tensou Sentai Goseiger and Kaizoku Sentai Gokaiger sets of costumes. At the moment, Ninja Steel is set to be the first exception to this rule, as the Super half will be the 25th anniversary, yet the series is on its 22nd set of ranger suitsnote whether or not this trope is played straight with the 30th series will depend on if Saban stays on Nickelodeon, since due to Nickelodeon's "20 episodes per season" rule, Saban has been skipping even numbered Sentai series, meaning that the 30th "Power Rangers" series will adapt the 45th Sentai series and have the 24th set of costumes, while the 35th series will adapt the 51st Sentai, and have the 27th set of costumes.
Subbing vs. Dubbing: In this case, "subbing" means being as faithful as possible to the source materialnote best exemplified by Wild Force, Time Force, and Samurai and "dubbing" equals Pragmatic Adaptationnote best exemplified by In Space, Lost Galaxy, and RPM. Notably, this debate only applies to the franchise's internal politics; "dubbed" series tend to be better received by the fans than "subbed" series (with the exception of Time Force).
Surprisingly Improved Sequel: A case could be made for the early seasons, as the show went from an almost plotless beat-em-up to... well, having plot.
With the Gokaiger footage coinciding with the series' 20th anniversary, you'd think it would make sense to go from Super Samurai straight into that. Unfortunately, Saban was contractually obligated not to skip any Super Sentai series, and Nickelodeon had messed things up by halving the number of episodes in a season, forcing Saban to split the Shinkenger adaptation over two years. The best Saban could do at that point was to merge Goseiger and Gokaiger into one story, so that Gokaiger is at least closely related to the anniversarynote makes things even worse when you consider that a large amount of the tribute episodes in Gokaiger were of seasons adapted into Power Rangers; thanks to having to merge Goseiger in with Gokaiger, however, they had to resolve plot threads from the first half (which adapted Goseiger) in Super Megaforce, meaning that a good amount of tribute episodes were not adapted.
The original Black Ranger was black and the original Yellow Ranger was Asian (the producers did not realize what they had accidentally done until several episodes in, when it was too late to change anything). This is furthered evidenced by The Galaxy Ranger Promo that Saban made for Bandai in 1992 (likely made of original footage made for a Bioman pilot) in that Zach was Biorhythm Green and Trini is Biorhythm White.
Parodied in thisCollegeHumor video, which portrays Zordon as a Politically Incorrect Hero who designates his recruited team's Ranger colors based on minority. In addition to deliberately choosing the black recruit and the Asian recruit to be the Black and Yellow Rangers, he appoints a Jewish recruit to be the Green Ranger because of the stereotype that Jewish people are obsessed with money, he makes another black recruit another Black Ranger, and he makes a female recruit the Pink Ranger just because she's a girl.
The Rangers have occasionally made poses that look strikingly similar to the Nazi salute. (As pointed out in gifs like this)
Vindicated by History: Most of the seasons with negative receptions tend to get this in the years following their release, usually thanks to something worse coming along; the most notable examples are Turbo,Wild Force and the Kalish Era as a whole (Though Overdrive is still passionately hated in some circles).
Time Force is especially the one with the most grown-up subject matter. In the future, Designer Babies are the norm, and the resulting mutants are outcasts and became criminals just to survive. The Starscream turns out to be The Starscream because Ransik betrayed him first in his previous identity because he couldn't see past his hatred of humans even when one had just helped him. You get a story about man's inhumanity to man, villains we created and mistreated but who went from La Résistance, and off the slope into The Revolution Will Not Be Civilized, and the Cycle of Revenge. Yes, this is the same show that once had as a villain's plot, "destroy the Pink Ranger's parade float just to make her feel bad!" nine or so years previously.
Win Back the Crowd: Zig-zagged. In Space and RPM are fan-favorite seasons that considered some of the franchise's best; both followed Turbo and Bruce Kalish's run, respectively, which...aren't. Dino Charge looked to do this for the Neo-Saban Era, being the first season of that era that was unanimously considered good... then Dino Supercharge turned out to be more iffy than its predecessor, and Ninja Steel ended up losing the crowd again. Beast Morphers, thankfully, has turned out to be a major step up in quality, which is a promising sign for the still-fairly-new Hasbro Era.
X-Pac Heat: Will from Operation Overdrive is probably one of the most loathed characters in the franchise. The sad thing is, this doesn't have anything to do with the character himself (in fact, he used to be something of an Ensemble Dark Horse of the team), but when his actor, Samuell Benta, stole a banner from Power Morphicon that was supposed to be auctioned off to charity (and afterwards smugly stated he had the banner and had no intention of giving it back) many fans turned on the character. Whens rumors popped up that Benta might actually be brought back to cameo in Super Megaforce in an Operation Overdrive tribute episode (which never materialized), fans rioted online.
Blake Foster got some backlash just from playing Justin in Turbo, but he really came under fire in 2019 when it was revealed that the Gold Ranger in Beast Morphers would be Nate, the small and nerdy tech-guy of the team. Foster called him a "weenie" and didn't stand out amongst the team, and the fans rioted and pointed out that he was quite hypocritical considering the amount of hate he used to get. Fortunately, since then he's apologized to Abraham Rodriguez (Nate's actor) and the two have made up.
