[fucker]

im sure someone else have named it already but ill suggest it anyway

watch Wolf's Rain. one of the best anime i have seen

i dont know it is, probably its atmophere, but it has moments of pure emotions (both positive and negative)

Spoiler Alert, click show to read:

and as every good anime, it has a great "wtf?" ending

EDIT - and for some good bloody action, watch Claymore
