This has got to be one of the best anime I have in seen in a long time. Got the box set on a whim after reading a few reviews on it, and never regretted it.
It is probably not everyone's cup of tea, being alot slower paced than it first appears, and the fight scenes that do occur are few and far between, being more an analysis of the characters and their inner workings. If you like philosophy, working things out without having it spoonfed to you, and bizarre mindwarping experiences then you will most likely enjoy this.
Oh, and Pino has to be one of the best characters ever!
