Durarara!! (up to episode 8): It's getting more interesting and more momentum by the minute, though not much has been revealed just yet. I'm excited to see more. Oh, and Celty's head is pretty.
Gintama (up to episode 15): The show is a very good boredom reliever and it's surprisingly emotional at times. And I hear it's going to get better from here on out, so I'm very much looking forward to that.
Aria the Origination (up to episode 10): Aria has been one of the most consistent series in terms of quality and this season is no different. The art has been cleaned up very well and stories are told so effortlessly yet masterfully that one can't help but smile by the end. I've only been disappointed once thus far, and that's Alice's super-special episode, but that's because I was spoiled of what happened. However, I was not spoiled the second twist in that episode, which rubbed me the wrong way. Only 3 episodes left, but I don't doubt that Aria will amaze me in a way that I'll forget I ever had a disappointment with this series.
