There's an entry and review up for it as well, for anyone who cares for a more comprehensive opinion:
Kara no Kyoukai - The Garden of Sinners Review - Anime-Planet
I for one thought it looked stunning - very atmospheric, loved the camera angles and the pacing was interesting. Action sequences are great too. My only complain is that, released like this, the story is going to be slow going. The first movie I think is far more interesting for its presentation than for the story and characters (I actually had problems understanding exactly what the hell they were talking about) so what's keeping me going is the hope that everything gets explained.
