But my own favorite shows are Chihayafuru, Kimi to Boku, Ben-Tou, Guilty Crown, Haganai, and Last Exile. Mirai Nikki is pretty powerful, too.
Anyway, here's the list, in alphabetical order, with some comments:
● Ad-lib Anime Laboratory -- Katou Emiri, Fukuhara Kaori, and a guest (Sakurai Takahiro and Kobayashi Yuu, so far) ad-lib lines from which a short anime is then made. Highly enjoyable for watching the seiyuus work, but the anime produced aren't that interesting.
● Ben-Tou -- Absurdly hilarious story about supermarket battles over half-price bentos. No, really. Yuuki Aoi is terrific as the fujoshi battle-watcher. So is Kayano Ai as the vicious class president. Good work also from Ise Mariya and Shimono Hiro. Sleeper hit.
● Boku wa Tomodachi ga Sukunai -- Friendless misfits of various kinds create a club whose aim is to make friends. Funny and well produced. One of the most popular shows of the season.
● C³ -- Oonuma Shin (ef melodies/memories, Baka to Test) brings us his smart version of a harem comedy, with real comedy, good animation, and lots of fanservice. And Tamura Yukari is terrific as the loli superbeing. But there is something missing, for me.
● Chibi Debi! -- Ten-minute episodes about a young girl who finds a demon baby in her bed. Nicely done, but not as enjoyable as I hoped.
● Chihayafuru -- Top-notch show following some well-rounded characters into the world of karuta, a Japanese card game based on classical poetry. Best of the season so far, for me.
● Fate/Zero -- Good first episode begins to wander in second ep, drifting back toward the monster show I abandoned in F/SN. Not my thing, so I can't really judge it. But this is the most popular show of the season, both in Japan and abroad.
● gdgd Fairies -- Short episodes of not much animation and a lot of talking. Not very interesting, for me, even if it is basically a seiyuu showcase.
● Guilty Crown -- Done by the same writers who did Code Geass, and it shows. But this has a sharpness and elegance of its own, and Kayano Ai as the central point of fanservice and magic continues to show she is the real thing. Much-watched, but with many negative voices. The writing seems pretty slap-dash, to me. I look forward to it every week, but can't rate it that highly.
● Hunter × Hunter -- Entertaining shounen comedy adventure. Not my thing, but excellent through two episodes. Fans of the original show are less pleased, and want the old cast back.
● Kimi to Boku -- Slice of life featuring a group of high-school boys. Some complain they are not enough like boys, more like the K-On girls in male drag, but I find the show gentle and enjoyable, and the boys seem like some boys I knew in high school.
● Kyoukai Senjou no Horizon -- One of the most highly anticipated shows of the season, with an interesting and complex background, and lots of fanservice. Ponderously slow at first, but the highly visual episode five was excellent. Probably the second most popular show, both in Japan and abroad.
● Last Exile -- Ginyoku no Fam -- The highly anticipated sequel got off to a good start, painting a broad canvas full of action and populating it with sharply drawn characters. The connections with the original show are beginning to come out as we reach episode four.
● Maji de Watashi ni Koi Shinasai!! -- Fanservice and romance in a school that teaches mecha fighting. If you liked Infinite Stratos, maybe you will like this. Neither did it for me.
● Maken-Ki! -- Boobsalot and not much else.
● Mashiro-Iro Symphony - The color of lovers -- Pure harem anime that works for me. Romantic feelings.
● Mirai Nikki -- Is doing a great job of adapting the manga. Looks like a good one.Yuno is in the running for top yandere shoujo of all time.
● Mobile Suit Gundam AGE -- Kiddy Gundam, but none the worse for that. I was riveted by the first two episodes, but then my attention began to wander.
● Persona 4 -- Nowhere near as smart as it thinks it is. A disappointment to me through two episodes.
● Phi Brain: Kami no Puzzle -- ditto
● Sekai-ichi Hatsukoi 2 -- Another warm bath in a gay male world of shoujo publishing.
● Shakugan no Shana III (Final) -- I'm sure I'm missing something, but I wrote this franchise off long ago as "monster of the week." The first part of the first episode seemed well produced, but it wasn't for me.
● Shinryaku!? Ika Musume -- Cute, but doesn't come near my funny bone.
● Tamayura - Hitotose -- Can this be better than the OVA? Perhaps it can. Sentimental to the Nth degree.
● Un-Go -- Started slowly, looking like an episodic detective mystery. But depth and complexity are beginning to appear.
● Working'!! -- Well done, but perhaps one season was enough for me.
