Been watching the following Claymore, Gunslinger Girl, Durarara!!, Disgaea, Black Cat. Dropped Disgaea because its garbage, Black Cat is almost as boring and I might drop it too.
Gunslinger Girl is interesting, the setting is Italy (I'm currently studying Italian, so bonus points for that), and although the main idea of "girls were trained to be killing machines" isn't very compelling, the series hasn't really focused on that and instead decides to explore a little bit of the girl's pasts and present life. There's drama but it all feels so... Calm, not rushed at all. And the ending theme is awesome (sampled a Faure song).
Durarara!! Isn't what I expected. Thought it would be some crazy over the top fighting or comedy series, but it's definitely something else. Which is interesting because I see what they're doing with their approach to storytelling, and I expect all these events/side plots to intertwine at one point. I've been taking my sweet time with this, but once I get a free weekend I'll catch up with it.
And Claymore is awesome. It's shounen, but not as annoying or generic as 98% of this type of series. Claire isn't exactly compelling, but I don't hate her. It's entertaining and there is a couple of storylines hidden underneath the flashy combat scenes.
If you haven't already, watch Baccano! Same author as Durararara. It's more action-packed and has a tighter focus but the ensemble style casting is similar. Most of the story in the present takes place on a single train, though much of the setup is told through flashbacks, so it's always dancing through time. It has some really awesome characters.
