That. Was freaking. Incredible.
Okay, where to start?...
The whole thing exuded kind of... um... a realness? Like it was really three-dimensional and you were just looking at it in animation. Particularly the cars, whose headlights looked very polished, by the way. The gore was extremely realistic (I mean, I've never really seen a guy with his top half blown off and guts strewn across the pavement, but if I had I imagine that's what it'd look like).
The detail was amazing. But I noticed that the guys in suits and the decapitated corpse, had more detail than the heroine. It was probably easier to animate her that way, and I understand, but it was a little noticeable. But that was the ONLY THING. This was totally great.
