Black lagoon was the first anime I ever watched, saw it streamed with a group of /tg/ers. I quite liked it.
In the past two months I got myself a case of labyrinthitis and a whole host of other things, leaving me stuck at home and bored to death, so I torrented it. I loved it, then I kept downloading more recommended things - I've gone through all of GITS (1, Innocence, SAC, SSC) and NGE (fucking ending) before moving to the more typical anime stuff (Gurren Lagann, Panty & Stocking with Garterbelt - good lord gainax are interesting.)
I'm about to hit Burst Angel, Bokurano or full metal panic, not sure which (the first two came up on recommended for those who like black lagoon.) With my somewhat limited knowledge of anime I think like all things there are some good and some bad for representations of fire-arms, but I like what I've seen so far.
