Suzumiya Haruhi no Yuuutsu eps 12 to 19 - I still don't understand how it's possible to watch the Endless Eight episodes and not totally appreciate what you're watching. I understand how it's easy to jump to a snap decision and love trolling, but that's another matter entirely. The level of fidelity is incredible, the merging of form and content perfect, and the areas in which the show always impresses technically (voice acting, sound editing and background music, frame composition) stand up to this most vigorous of tests.
The World God Only Knows ep 11 - I love libraries, and I love books, and this arc has been my favorite so far. Shiori is a wonderfully delicate character. Second half of the season has been so much better than the first.
Otome Youkai Zakuro ep 11 - When even a show's character names stand out as being especially beautiful, you know you're on to a winner. Tsukuhane's story was told just as well as everything else has been in this show, and it continues to be at the absolute top of this season's shows.
Fairy Tail ep 58 - Nice emotional episode, Lucy is a really great character, keeps the series feeling fresh. Not quite as good as the Loke/Lucy episodes, but high quality.
Fortune Arterial ep 10 - Built up the atmosphere really well, fairly predictable outcome but required for the series to come to a head. Has been fairly consistently entertaining when it focuses on the vampire side of things.
Milky Holmes ep 10 - Arsene's relationship with the girls is probably the only interesting part of the show, but overall this seems to have lost its way. G4 are the most entertaining thing going on by a long way. Having said that, I still find it vaguely amusing, but not in any way that makes me pay much attention to it while I have it on.
