Bakemonogatari 1! Probably has the best animation quality out of all the shows currently airing.
+ High quality Shaft animation
- but not liking their style of perpetual on-screen text
+ Hiroshi Kamiya!
- a tad verbose
Quick impression~ A girl falls from the sky. A boy catches her. She staples his cheek. He decides to help her. When I read the summary, it initially reminded me of Mushishi, Natsume Yuujinchou or xxxHolic, where a male character gets involved with the supernatural. I've been meaning to post a review of Nisioisin's xxxHolic novel up, but man, Watanuki and Yuuko have more dialogue in one of his chapters than they have in 15 volumes of manga. Anyway, Nisioisin tends to riddle dialogue with references ranging from pop culture to historical facts and myths. The first episode of this gives you a taste of his writing. The episode is great at establishing characters that you want to see more of.
