Of all anime out there, that could be adapted into live-action, anime such as Monster, Paranoia Agent, Berserk, Fist of The North Star, Legend of The Galactic Heroes, etc. all of them have a semi-realistic art style and are somewhat down to earth, those could be adapted into live-action, but they choose to adapt the most cartoonishly shonen out there, this is going to be a trainwreck, but that's probably what they're going for, something like "People are going to watch this to see how bad it is, right?"
