I definitely liked the movie, but I'll say right now that Kamen Rider Joker did nothing for me. I was honestly disappointed that it wasn't a Joker Dopant instead. the movie-exclusive dopants are just so much more interestingly designed, and heck, it would've been even more cool to get an Accel Dopant and Eternal Dopant as well, but Kamen Rider Joker was just uninteresting to me. Also, if not a Joker Dopant, it would've at least been nice to see KR Joker be more unique than just JokerJoker without the silver stripe and a Lost Driver. To actually have him look like a Joker/Jester would have made him so much more appealing.
Eternal OTOH was a much better movie rider. Well-done design, cool to see a rider who fights with a knife rather than a sword, and the way he used all those memories was purely awesome. It makes me glad he's getting a V-Cinema as well as Accel. Speaking of which, I totally enjoyed Accel's fight scenes, though feel he should've had more, or at least more time as Accel Trial. Of course, the V-Cinema for him will remedy that.
But yeah, definitely a good movie
edit: On second thought, Joker is pretty cool, but not because he's compared to BLACK. In my mind, BLACK is and always will be a lame rider with a lame suit design, and so Joker being compared to BLACK kinda stirred a dislike of him in me. Joker is cool as his own rider, not as an homage
