I'm searching for some really good animes that are NOT mainstream, meaning that not EVERYBODY knows about them. Bleach, Naruto, Inuyasha, and Full Metal Alchemist, for instance, do not count.
So far I have checked out the following.
Black Lagoon - I like the action. My complaints are that it is totally unrealistic and serves only to entertain with gun action.
.hack signs - I like the concept, but I think they talk too much. My personal tastes are more action, and just enough talking to motivate the action, but not so much that it gets boring. Yeah, not everyone knows about .hack signs.
Serial Lain - Very original in creepiness. I liked it but I didn't get very far in it.
Airmaster - The fights are awesome. I'm looking at it right now.
