I can see a Hollywood exec being wowed by the elvator pitch you could make about this "It's Fast and the Furious meets Guardians of the Galaxy" This could be adapted into a popular summer Hollywood movie. It's got great action, unbelievably good character designs, an easy to understand plot, fun characters and it's filled with fun.
That said, a Hollywood adaptation would probably add unnessecary subplots, cut down on the action, make it less weird and cut the topless scene - so let's be happy that this is what it is- a near perfect anime action masterpiece!
Also, the bluray picture and sound are magnificent. Watch it with your sound system cranked for maximum pleasure.!
