Episode 4 brings us a graphical OP sequence. To cut to the chase, it's absolutely brilliantly insane. Sparse, yet intensely fast-cutting, with a surprising dose of overt, yet repressed, sexuality (if that makes any sense). I was absolutely floored the first time through.
This is a good time to appreciate the use of textures in this show. There's this feeling of authenticity, of harmony, of just plain aesthetic coolness. I can't find the words at this hour to fully express my enthusiasm, but man, this show is hip.
