Saw it back when it was released though wasn't overly excited after watching it. From what I recall without revealing too much its about a boy with some obvious lacks of social intelligence/life in general and blends in his archlord character(not in a good way) with his irl issues bla bla.
you might get more out of it if u watch it with subtitles though, i watched the entire movie without, and i dont even know dutch, lol.
