For a big part of this movie I was totally confused because so far, I've only seen Kamen Rider Build in its entirety and just bits and pieces from the rest. But one thing it achieved perfectly? Now I want to see ALL of the Kamen Rider series and learn all of their stories! So, I guess it was a success, heh.

This movie also reinforced my love for Sento - and by extension for Inukai Atsuhiro - because Sento is such an amazing character, so incredibly smart and brave and silly and cute and so very excitable. And such a good egg on top of all that. But also so... well, wise, if I dare say so? Because I loved the scene where he and Sougo talked about the possibility of them all being just imaginary and he said, well, so what if we are? It doesn't matter. As long as one person remembers us existing? We did.
Also, the scene where Sento got all manhandled by the baddie? That was very... suggestive. Like VERY suggestive. That guy was all over Sento O.O

Also #2, wow at the cameo of Satoh Takeru! How did they manage to bring a star of his caliber back? Wow. Oh, wow. The whole scene was so cool! Now I really want to finish Den-O!

Overall, a really good movie with some ah-mazing fighting scenes. And a perfectly delicious invitation to watch all the Kamen Riders showcased there! Yuss!
