read carfully!
Being someone who notices details, there were many many many many many many many many many continuity problems (stuff that changed instantly without purposefully happening, as in you didn't notice it). And only in the last 3 episodes did the animation get to be decent. Also, the voices dont match the appearence of the characters.
Just as an example of a continuity problem:
in one of the earlier episodes, he crashes into a car, then instantly drives forward (which would be throught he car) when someone notices him.
also, in episode 10, why are they speaking in japanese or chinese or whatever, but reading english?
