If I had to choose only one, it would be Kamen Rider Saber: Trio of Deep Sin. Totally unusual (not only within the franchise, but also as a movie in general), very soulful and beautiful, and overall a thing that I highly recommend watching. Other favorites (I try not to choose the most obvious ones, which will definitely be mentioned by others):
- Kamen Rider Gotchard: Graduations. Despite its simplicity and short running time, it sank into my soul. Also a very soulful movie, which made me sincerely worry about Spanner, although throughout the show I was indifferent to the character.
- Kamen Rider Wizard in magic land. A rather simple movie, which clearly lacks the budget for its idea, but I am captivated by its ambition. Plus, the final battle is gorgeous. And there is also river mayonnaise and incredibly funny extra shorts.
- Kamen Rider Faiz HBV. An incredibly funny mini-musical. I know I won't get any support for this, but for me, this is the best part of Faiz.
- Kamen Rider Agito: Project G4. It's strange that it's not mentioned much, but it's the first full-fledged Rider movie related to the show. And both the plot and the special effects look good even now. I especially like the similarities between the human and the kaijin villain.
- Kamen Rider Shin. Prologue. I'll keep saying this until Toei listens: Shin deserves a happy ending. If they resurrected Takumi after 20 years, then Shin has a chance too.
