MMM, you liked Gantz?
who would have thought...
i would say. these ones besides all the mainstream like Death Note etc.
1. Pumpkin Scissors
2. Break (Broken) blade
3. "Kino no Tabi (Kino's journey)*The beautiful world" is probably one of the best animes out there in terms of philosophy.
4. Requiem for the Phantom. cool series about a guy and a girl who both are brainwashed to be the prefect killers.
and movies...em. Panyo.
or "toki wo kakeru shoujo" meaning "girl who leapt time". just so perfect anime movie. beautiful, funny and just all around enjoyable.
also "Aoi Bungaku" which would be "blue literature". episodes are based on several famous Japanese works. it's perfect if you don't have the time. it is 12 episodes and with 4 great but different stories each taking up 3 episodes.
