JoJo no kimyô na bôken: Daiyamondo wa kudakenai - dai-isshô

First of all I am not familiar with the source material, so I can only judge the movie on its own. It is stylish and well made cinematographically and the opening act sets up an intriguing scene, but then it just falls flat. The characters don't really develop relationships and the story is totally superficial and boring. There is no deeper meaning to it whatsoever. It's like watching a bunch of kids play a computer game where they have their colorful avatars fight one another.
