It's hard not to compare this to the anime. When you do, you'll realize it's super different, and it doesn't live up to it.

Yes, it's a 2 hour movie, so they gotta cut some things out. I think they had cut out too many scenes of Haru and Shizuku in the beginning, because the pacing felt weird and too fast. The Natsume and Micchan love story should've never happened in the movie to give more time to Haru and Shizuku. Seriously, the Natsume-Micchan scenes were only like 3 minutes. It did nothing for the movie.

I feel like they tried making this story more realistic.... Except they didn't. Like, super strength and flying capabilities?!?! ???? They toned down the characters and cut back on 95% of the humor. I am SUPER DISAPPOINTED that it wasn't funny at all. They tried to make some of the beginning scenes funny, but without proper BGM, it was just super awkward and cringey.
And because they tried cramming the entire story into a movie, characters aren't given enough time to develop, so they end up being very different from their anime/manga counterpart.

Maybe it's the script or the pacing, but Tsuchiya Tao was super awkward in the beginning, but she got progressively better. Masaki Suda is entertaining as Haru. I think all of the characters were toned down, except Haru, so he feels super over exaggerated. That shade of blonde on Yamaken was just UGLY. The actor for Sasayan was cute, but he's got a mature face IMO. He looks like he's in his mid to late 30's when he's only 27 (and playing a highschool student).
