It is, quite possibly, my favorite action series ever. You've got a relatively honest, hard-working former salaryman joined by a much-abused and much-abusing (and very hot) gun-toting near-psycho, a former Marine, and a super-hacker, all come together to work as modern pirates.
Yes, it's Black Lagoon, with as much heart and soul as it has blood and violence (and that's quite a lot). Moon Phase reports that a third “season” will be released as an OVA in 2010. Director Sunao Katabuchi returns, too. I wonder if it'll be any more violent and graphic than the past TV series?
Now, obviously we aren't caught up with the manga in Japan, although all of the past two seasons of the anime are out. Assuming the new OVA follows the manga, I believe the next arc features the return of a particular umbrella-toting maid. I've also heard it's a very dark and somewhat trippy storyline, so it'll be interesting to see how that goes.
