After one episode, so many shows seemed enjoyable. After three to five, the list has grown shorter.
This is all just personal opinion, a combination of judgment and instinctive preference. Read at your own (and my) risk. (mouseover images for captions; click to enlarge)
Darker than Black 2 -- Hanazawa Kana is just outstanding in this slightly gentlified second series of the dark sci-fi adventure. She has taken her voice-acting to a new level. This is the show I am most eager for every week.
Winter Sonata -- I'm sold. Great music. Great images. Great story. Fantastic characters. A high school tsundere who seems real.
White Album -- A huge edifice of uncertainty and suppressed emotion is about to come crashing down. Whether it will all make sense as it does is still uncertain, but the complex spiderweb of feelings and events is a painful joy in itself.
Seitokai no Ichizon -- The show this season about which there is the most intense disagreement. For me, it is a hip, smart, hilarious and humane self-referential comedy with great characters, total absurdity, and moe to spare.
Yumeiro Patissiere -- A show aimed at elementary school girls that manipulates its memes with complete assurance, creating warm sentimental emotion.
Tegami Bachi (Letter Bee) -- Charming fantasy. Excellent voices. Wonderful direction by a newcomer who makes each episode just fly by.
Aoi Bungaku -- The source material is so strong that even when they change it around, it's still powerful. At least through the first four-episode story. Almost too strong. I can sometimes hardly bear to watch.
Sasameki Koto -- Has now gotten rolling with the bizarre yuri comedy of the manga. The tall karate-expert loves her best friend, who gets crushes only on cute girls -- and now on the cute trap who loves karate girl. Get it? And the yuri wolves are out, too. Takagaki Ayahi (karate girl) and Saitou Chiwa (cute wolf) are both outstanding.
Kimi ni Todoke -- I love the manga, but I'm not sure whether to praise the slow delicacy of this show, or to express impatience. Maybe it's the "I've read the manga" syndrome. I haven't decided whether Noto Mamiko is perfect or is overdoing it, baking a cake that's so sweet you can't taste the flavour. But Sanpei Yuuko and Sawashiro Miyuki give award-worthy performances as Sawako's friends. And the character design and backgrounds are excellent.
To Aru Kagaku no Railgun -- Well-made girls-with-powers comic adventure fantasy. More enjoyable than Mai-HiME, for me.
Sora no Otoshimono -- Redefines ecchi. Famous for the ED featuring flocks of flying panties. Humor that is nutso without quite reaching the level of the absurd. Hovers on the brink of abandonment, but I can't resist Hayami Saori's voice.
Watching when and if I have time:
Fairy Tale -- Well-done shounen comic fantasy adventure, with Hirano Aya in her next big role. But not my thing.
Trapeze (Kuuchuu Buranko) -- Beautiful, brilliant, and bores me. I'll keep trying, but there's something arch and superficial about it. Or perhaps that's just me, lol.
11eyes -- Enjoyable supernatural adventure, but I don't find myself making time for it. Maybe it's my aversion to monsters.
Tatakau Shisho - The Book of Bantorra -- Also decent, set in a strong, dark world, but the weeks seem to slip by with new episodes unseen.
Miracle Train -- Episode one was okay, but I haven't yet felt the urge to go back and see what sort of girl the bishies help next. Too many good shows, too little time.
Kampfer -- Having abandoned all pretense to plot and character, we are left with fanservice alone.
Kobato -- I enjoyed the cuteness of the first two episodes, but have been bored silly ever since.
Seiken no Blacksmith -- I liked the first two episodes more than many people, but this is not interesting enough to warrant the time to watch it, for me.
Anyamaru Tantei Kiruminzuu -- Popular with the Japanese "family" TV audience, and completely uninteresting for me.
Kaidan Restaurant -- See above. These two shows have the highest TV ratings among new anime.
Nogizaka Haruka no Himitsu 2 -- Having enjoyed the first half of the first season, I watched two episodes of this second season...and quit forever. Can't keep pressing the same button.
Kiddy Girl and -- The worst show of the season. The animation is okay. What is being animated is of zero interest, period. How low have you fallen, Gotoh Keiji? Uta~Kata was a wonderful show.
I realize some shows are missing here. Those are shows I just haven't watched enough of -- yet -- to judge.
