Which aspect of Black Lagoon are you interested in? The violence would be easy to find, as well as the style of group like Lagoon Company. However, off hand I don't know of any anime with such blatant use of tobacco, alcohol, and language.
Well I do like all those things you just mentioned;) As for other anime's not having such blatant use of tobacco, alcohol and language, i'm kind of surprised :o
I do want to say that this is the first real Japanese anime that I have ever watched, (excluding stuff like Dragon Ball Z and Pokemon when I was younger) I like the characters and the dialogue a lot, the action scenes are well done and feel very cinematic. There has been times when I catch myself saying "Damn they should make this into a real live action show".
It doesn't feel like what I would expect an anime to be.
When my brain thinks anime I expect big crazy hair, giant mechs, androgynous main character who overall story arc involves saving the world, maybe some summons thrown in there for good measure…I guess I expected something like a Final Fantasy game. (which i'm not saying is bad at all)
I like the grounded in reality aspect of Black Lagoon, not to say that it's realistic, but it makes me feel as if this stuff could happen.
I do like some crazy though, like The Maid episode where she is messing up everybody to get back the "young master", that was fucking rad.
So yeah that's what i like about it, any ideas?
