I know this is based on an anime (which I haven't seen), so I went somewhat naive into this movie. I didn't know what to expect, the summary sounded interesting and there was Sato Takeru.

As I watched the movie, I realized once again that only Japan can create that kind of varying atmosphere. It started as some depressing slice-of-life genre, transformed into some fun Sc-fy action, jumped into the Death Note universe and came back for some superhero clash.

Two people of different age and circumstances stumble upon the opportunity to actually try out a "What would you do if you had god-like power"-situation while turning their innermost body parts into a superhuman robot. Due to their varied life experiences, their paths divide into completely different directions. Even though there's an explanation for the cause, they don't reveal the purpose of it all, and instead focus on the main characters development. You know pretty early on that there will be a hero and an anti-hero.

They use stereotype ruthless public bashing to corner the characters even further. Since there's no bloodthirsty psycho, there's no exaggerating use of gore either. But there is a very high death toll that makes you swallow nonetheless because of its simplicity. Like snapping fingers it happens without creating tension, no extensive explanation and delay. Just like that, it hits you in the guts (and that might not be to everyone's liking, just so you know).

CGI was totally okay in my eyes and the constant change between background music and silence I liked as well.

I don't think it's a movie for some real deep thinking. There is that question "What if...", but it's just that. The rest is either to people's liking or not. I for myself enjoyed the movie. And Sato Takeru can definitely pull off a high school kid.
