Diary of Tortov Roddle, eps 1-6 (finished): Only took 15 minutes to complete the entire series of shorts. The art is very European-esque for an anime (much like Petits Cubes). I don't want to call it a "trippy" experience, but it was rather one of those, though it's not necessarily a bad thing. It's reminiscent of the imaginative side of young children and old cartoons.
Heroman episode 1: Stan Lee's creation, so I was all too curious to not see the first episode. The artists did a good job of rendering an American city, because all the sights were familiar: the suburbs, recycle bin designs, cars, and
Brutalist architecture. The story itself is rather generic, but nostalgic for Saturday morning action cartoons. Vibrant colors all around in this one, and art is also great. The biggest problem is the main character; to put it bluntly, he's a wimp, and that's a problem since he's supposed to be the main hero (aside from the robot that he controls).
Angel Beats! episode 1: I was really hoping for more drama, though knowing Key's work, it's a typical beginning to a story. Music and art direction were wonderful and in very high quality. Still, not much to say as of this point, though I don't see where the comparison between Yuri and Haruhi is coming from.
Kaichou wa Maid-sama episode 1: Wanted to try one more new series this season, and a shoujo one. I think I was least impressed with this one out of the three to be honest; art and animation direction were not up to par with the other two, and the characters aren't really pulling me in. I'll put this one on-hold until I hear good words of future episodes.
I vote for Misaki for bishoujo of the season, though.
