I am going to absolutely blunt here: it was shit. But it was funny shit. I’ll elaborate on that a little.
I understand that, for a movie adaptation of a long long series of something, be that anime or manga or any other form of media, some changes have to be made, especially when your target audience is from a very different culture to the one it was originally built for. But this? Who the hell were the target audience? I do not understand who this was supposed to be for: the fans, teenagers, B-movie enthusiasts? Whatever few references that they made to the original manga or the anime adaptation just felt cringey to me as a fan, so I don’t think that’s it. It’s a bit too gory for teenagers, but the plot and the use of shitty pop music absolutely makes it feel like one. So was it made for B-movie enthusiasts, among which I count myself? Perhaps, but even for that it was not very good.
