YMMV / Kamen Rider × Super Sentai: Super Hero Taisen

• Big-Lipped Alligator Moment: During the trip back to the Goranger era, Baseball Mask shows up yet again, only to be unceremoniously killed off in one shot. Besides Joe and Don recognizing him, he never ends up having any importance at all.
• Broken Base: Arguably the most controversial toku movie so far, with some people liking it for its action and seeing Sentai and Riders together, and others hating it for its lackluster and/or mind-screwy plot (depending on who you ask) and not exploiting the crossover to its fullest beyond the final scene. Although the future crossovers would have similar problems.
• First Instalment Wins: Compared to the increasingly divisive future Super Hero Taisen films which got their fair share of criticism for having even more nonsensical plot points or mischaracterizations for the sake of conflict, this one is much more forgiven and fondly remembered in spite of its flaws.
• Fridge Brilliance: In the final battle, it's very fitting that Fourze ends up piloting the RH-03 component of Go-Buster Oh. Considering it's rabbit theme and the fact that Fourze and the Kamen Rider Club have a secret base called "Rabbit Hutch".
• He Really Can Act: Yuki Yamada, Joe Gibken, has a few hard-hitting emotional scenes in the middle of the movie. While he wasn't bad in Gokaiger per se, he never really got to do much outside of being stoic and looking cool most of the time, at least when Joe wasn't confronting Barizorg. If you didn't consider his acting in the series all that captivating, just watch his scenes here.
• Hilarious in Hindsight:
  • So Marvelous is after the Best Treasure of the Kamen Rider 'verse, huh? Obviously, trying to find the Second-Greatest Treasure in the heart of the Zangyack Empire didn't work out for him. Or maybe it did and he just wanted more treasure.
  • The final battle has a teamup of Kamen Rider BLACK and Hikari Sentai Maskman, two series running concurrently during the late 80's. In other words, if Super Hero Time existed back then...
  • Sometime after the movie's announcement, the producer mentioned they could do more in a crossover movie than they could in a series because "Rider is science, Sentai is magic." Well, now Rider is magic, too. And one Sentai had science lessons at the end of some episodes and one Omake.
    • Made even funnier considering the first series to run alongside Wizard is one of Sentai's technology-driven series and not a magical one. (Although neither Rider or Sentai's "science" would be worthy of a Science Channel special)
  • Another mecha has already beaten Go-Buster-Oh to having a "Rider Kick", let alone a drill-infused one.
  • At the end of the movie, Fourze declares that he makes it his mission to befriend every single superhero in the universe. Considering 2012 saw the boom of a large number of superhero movies across the Pacific...
  • The Riders and Sentai emerging from Decade’s dimensional walls to face Dai-Shocker and Dai-Zangyack draws parallels to the famous “Avengers, Assemble” from Avengers: Endgame seven years later, as demonstrated by slapping Endgame's "Portals" theme onto said scene.
  • The Net Movies acknowledge that Super Sentai aired alongside Metal Heroes for a good many years before Metal Heroes were replaced by the Heisei Rider revival which started in 2000. In 2013, the Metal Heroes join the fray in Super Hero Taisen Z, then 2014 has the modern Heisei Riders duke it out with the classic Showa Riders in Kamen Rider Taisen.
• Ho Yay: Kaito and Joe. Also Kaito and Tsukasa, to the point that in their first conversation, there's romantic-esque music in the background.
• Just Here for Godzilla: If you're looking for a well-written plot with a logical flow of events, this probably isn't the movie for you. If you just want to see a whole bunch of Kamen Riders and Super Sentai onscreen though, you'll enjoy it.
• Memetic Mutation: This movie will be the cause of the end of the world predicted in the Mayan Calendar.
• Narm:
  • No one can really take Tsukasa's unmorphed scenes seriously because of his hairstyle, which earned him the nickname of "Granny Tsukasa". Surely enough, Tsukasa has not donned that hairstyle in future appearances.
  • In the scene where the Riders face Narutaki as Doktor G, Faiz's reaction to getting blasted the first time is jarring (he goes for a sword slash that would have missed, and pauses mid-motion before getting blasted, taking quite a bit of time to react to the hit). When Narutaki unleashes the second wave of blasts, Blade and Ryuki run up, before stopping, turning to run, then getting hit, with Blade doing a weird jump.
• The Scrappy: Daiki Kaitou gets a lot of flak for his portrayal in this film, particularly in the climax where he sides with the villains and pilots the Big Machine against the heroes, simply to get revenge on Tsukasa for lying to him.
• Shocking Moments: The announcement alone, and then Toei graces us by tallying the number of heroes: 240.
  • On top of that, scans show that GoBuster-Oh, the Go-Busters' Humongous Mecha, will use Fourze's Super Rocket and Super Drill Switches.
• They Wasted a Perfectly Good Plot:
  • More of a scene than a plot point. It would have been VERY COOL to see the Gokaigers fighting in OOO's forms rather than just using the keys to fuel Gokai Galleon Buster.
  • They could have also shown what was going on with Fourze and the Go-Busters during the whole debacle with the Gokaigers. Hell, some additional interaction between the Gokaigers and the Go-Busters would have been nice (though of course, that'd make the traditional Go-Busters vs. Gokaiger redundant, which helps explain why interactions are at the bare minimal).
    • Fourze and The Gobusters as the currently airing shows when the film came out were kept minimal deliberately, both for practical purposes (both shows were still filming regular episodes at the same time so the actors were mostly busy doing that and could only film a few short scenes for the film) and marketing ones (it wouldn't do to have the current heroes with their merchandise still on the shelves get defeated by characters from older shows, hence why the Gokaiger rescue both of them from their defeats by Marvelous and Decade and they promptly vanish from the story until the final battle when the Riders vs Sentai bit is resolved)
• Unexpected Character: Bio Hunter Silva returns as one of the chief antagonists after nearly 30 years of not appearing in any Super Sentai instalments, considering how Sentai in general rarely brings back villains from past series after a maximum of 5 to 10 years, let alone one from the Showa era in a major role, his return was very well not one everyone could've seen coming.
