The animation wasn't really anything special; it was about the same quality as the series.
I really wasn't expecting an Ushiko-Umao reference in the movie. It's been a while since I watched the series, so it was just a nice surprise and probably the only really funny part in the movie.
Spoilers below, it's hard to talk about the movie without spoiling it since he makes his decision sorta early in the movie. It's based more on their feelings and how things go after that, not indecisiveness.
Kyosuke finally tells Hikaru how he feels in this movie. It's pretty tough, but... well, it was always very one-sided from the start. She was always just pressuring and forcing him into stuff simply because she thought he looked cool the day he used his power to shoot a basketball through a hoop? I always thought Hikaru just seemed really shallow and stupid, so it's pretty easy to accept her defeat.
The movie starts off in black and white as if to set a more serious tone... it also ends in black and white after the story is explained and it returns to the point where the intro ended. Something about this feels just feels kinda incomplete... It didn't just set a serious tone, it set a kinda depressing one, like all the fun's been sucked out since Hikaru's been turned down. Are Kyosuke and Madoka happy together? They sure didn't make it look like it. Did Hikaru accept reality? I dunno what the point of her "bang" at the end was. The black and white thing makes me feel like the two aren't happy and like Hikaru didn't move on...
The movie gave the conclusion we were all waiting for, but it could've tied things up a little better, I think. It doesn't handle that very well by itself, but the second movie gives a more concrete ending.
