Alright, here's what I'm watching this season and my opinions. And yes, I'm watching 24 shows this season.
Arpeggio of Blue Steel: Ars Nova - All CG takes some time getting used to. Interesting story, decent music, nice character designs.
BlazBlue Alter Memory - Haven't played the games but the story direction seems like a mess. Animation is a little on the not-great side, but the first fight between Jin and Ragna is pretty good.
Coppelion - The writing is terrible and the main character is bipolar. Animation is not good and the music is overly dramatic. Also, angela's vocalist can apparently sing but chooses not to do it very well in the OP and ED.
Galilei Donna - Decent animation, good character design. The over-the-top evilness of the antagonist is pretty funny. It's ok, nothing amazing but it's directed by the guy who did Kite and Mezzo Forte, so we'll see.
Gingitsune - Supposedly a seinen series, but feels pretty shoujo. Not bad, a little on the boring side since it's slice-of-life but it's enjoyable. Supernatural/mythological stuff is always a plus.
Golden Time - Not sure how to feel. It's JC Staff, so even if you have a catchy OP/ED, the pacing is always a little odd. Not bad, though none of the characters are really likable (except the loli who has like 5 minutes of screentime).
Gundam Build Fighters - Seriously glad this has a more comedic direction. It's massive fanservice to Gundam fans and it's well-animated compared to Gundam AGE.
IS: Infinite Stratos 2 - self-explanatory
Valvrave S2 - dumb
Kill la Kill - just watch it
Kyoukai no Kanata - It's not as serious as you'd think, and also KyoAni moeblobs + supernatural stuff. And blood. Not bad, not amazing.
Kyousougiga - just watch it
Little Busters! Refrain - Continuation. More JC Staff. Can't compare it to the VN, haven't read it. I guess it's ok but the pacing is weirder than the first season.
Unbreakable Machine-Doll - Has the most irritating ED of the season. Yaya is a blend of annoying and awesome. It's alright so far.
Nagi no Asukara - Great animation quality. Nice little fairy tale setting. Main character's a bitch but he's growing up. Yes, this show has character development.
Non Non Biyori - your moeblob slice-of-life for the season.
NouKome - long loving title, comedy direction is kind of meh but you watch this show for the fanservice.
Outbreak Company - Surprisingly good, awesome amount of references and likable characters.
Samurai Flamenco - Hilarious, I think people should watch it.
Tokyo Ravens - Bad CG, weird pacing. Not great, not unwatchable.
Walkure Romanze - Based off an eroge, so it's kind of stuff
White Album 2 - Also based off an eroge, but it's not terrible. One of the better VN adaptions (so far).
Yozakura Quartet: Hana no Uta - This is good. Haven't seen the previous series or read the manga, but this is a reboot so the former isn't required.
Yuushibu - Fanservice show, it's a bit like Hataraku Maou-sama! in terms of its backstory. Likable characters, not bad at all.
