Well, I'm getting bored and just got back from a panel with Brad Swaile at Fan Expo, so I'll do my mid-season breakdown a little late.
Blood Lad (Finished Episode 7)
I watched this expecting a goofy romantic comedy adventure... I got that plus a F**KTON of references/shoutouts. That aside, the story's actually solid, the characters are lovable and goofy, and the art direction is great. I'm hoping that Braz gets the sh!t kicked out of him by Staz at some point, so I'm probably gonna have to pick up the manga once it's over.
C3-bu (Finished Episode 7)
It's Gainax's answer to K-On!... but better. The art is better IMO, the characters have a little more depth, and it has that expected WTF factor you'd expect from Gainax, namely a surprisingly dark turn in the recent episodes. It also has a godly ending song (sorry, I love Miyuki Sawashiro's voice)
Danganronpa (Finished Episode 7)
A visual novel adaptation, so no-one who's played it is gonna be happy with how it's turning out by comparison. I haven't, and I'm thoroughly enjoying the VN-esque direction of the show. A great cast, quirky characters, and enough WTF to throw me off my game. Good fun all around.
Fate kaleid liner Prisma Ilya (Finished Ep. 6)
Probably in my Top 3 for the season. No Nasuverse fan should be avoiding this. The quality of the show rivals Fate/Zero, and shines the spotlight on two of my favorite F/SN characters (Rin and Ilya). I pray this gets a Season 2.
Free! (Finished Ep. 6)
K-On! with better art, characters, writing, humor, music... and nearly naked men. I wouldn't rank this in the Top Shows of the Season, but it delivers on the hype a lot better than K-On! ever did. Also, where's Gou in a swimsuit?
Genei wo Kakeru Taiyou (Finished Ep. 4)
Picked this up late... and I wish I hadn't. It's a harsh show. Post-episode-3-Madoka harsh from Episode 1. Very cartoony art, but still great. Beautiful soundtrack and splendid voice acting headlined by Mai Kadokawa (also leading Prism Ilya) and Eri Kitamura.
Highschool DxD New (Finished Ep. 7)
Obviously, you're just getting more of what you liked in Season 1, so if you liked S1, this is just as good. Also, I love Xenovia.
Kamisama no Inai Nichiyoubi (Finished Ep. 4)
HOLY SH!T, this show is beautiful! Seriously, this is probably the most beautiful show of the season. The plot's not too deep so far, but in a show about God abandoning the world, causing a zombie apocalypse and the appearance of 'gravekeepers' who can lay them to their final rest leaves a lot of room for some really twisted stories.
Monogatari Season 2 (Finished Ep. 6)
Once again, as the continuation of Nisio Isin's wordy urban epic, you get more of the same you got from Bake/Nise/Nekomonogatari. The first 5 episodes are from Tsubasa's POV, which is cool given that she's one of the most... confusing characters of the show, but people who love Koyomi's POV will need to wait until Ep. 6 for things to go back to him.
Neptunia (Finished Ep. 6)
I know people hate that we got this instead of more Jojo, but I believe David Production's created an adaptation that both does it's own thing AND pays proper homage to the games. Fourth wall damage, video game/console shoutouts galore, and some loveable goofiness make for a lovely experience.
Servant X Service (Finished Ep. 8)
My god, this show is genius! There's some great humor and clever writing here. If you liked Working!!, it's from the same creator. Definitely in my Top 3.
Shingeki No Kyojin (Finished Ep. 18)
If you haven't been convinced yet, I won't even bother.
Symphogear G (Finished Ep. 7)
Another case of 'more of the same'. In this case, though, it's much better. The music is even prettier, the art is even flashier, and the writing is far better. The final part of my Top 3.
Watashi ga Motenai no wa Dou Kangaetemo Omaera ga Warui! (Finished Ep. 4)
I know the internet's loving this show, but I find it too depressing to watch on a weekly basis. I was never horribly popular in highschool, so the notion of someone worse off than me just makes me sad. Sometimes I laugh at Tomoko's despair, but it's mostly disturbing what can go on in her head at times.
