A twist from the usual blood&guts...
like many reviewers(male) said, i too, experienced the pain of being chased by some ugly&excessively desperate chick, so, action-wise, the movie depicted it very well, unfortunately, "graphic wise", the gurl didn't look like a cute bunny...
There are also other possible messages about racism, interracial(not species, fools)relationships, accepting/respecting differences of others, & even world peace(j/k), but u can find those reviews by swimming through the 1000+ reviews before me.
I definitely saw the Anime influence which made it easily, super-cute (i never knew i could type that),and of course the author's superior animating and drawing skills.
The music fit nicely since u can tell the author obviously went through some time animating with the music&rythm and synchronizing it with the animation.
A job well done, a language barrier well broken, a message well recieved.
btw, for the ignorant masses out there, check out his site before asking for english lyrics, which country he's from, or wut language the song was sung in. Even the song name is there, don't be lazy, and expect someone to hand-feed you every bit of shit you ask for
