I'm watching Aku no Hana, Arata Kangatari, Date a Live, Hentai Ouji to Warawanai Neko, Karneval, Ore no Imouto ga Konnani Kawaii Wake ga Nai, Photokano, RDG: Red Data Girl, Shingeki no Kyojin, Toaru Kagaku no Railgun S, and Yahari Ore no Seishun Love Come wa Machigatteiru.
In terms of favorite to least favorite, this is probably how my rankings will stay until the very end of the shows:
1. Shingeki no Kyojin - So far this anime has the potential of being the best of the year for me. I'll have to wait and see how it goes until the end before it can be the absolute best.
2. Hentai Ouji to Warawanai Neko - I really like romcoms for the most part. There are some that I'm not particularly fond of (like Toradora as an example), but this one isn't one of those. I think it is cute.
3. Yahari Ore no Seishun Love Come wa Machigatteir - See above. I also must say that this romcom has the best main male character I've seen in a romcom yet.
4. Toaru Kagaku no Railgun S - Sister's Arc <3
5. Karneval - I followed the manga for a couple years and thought it was pretty decent, so I was a bit excited for the anime. The anime is pretty decent so far too imo.
6. Ore no Imouto ga Konnani Kawaii Wake ga Nai - Honestly, the episodes without/with barely any Kirino are REALLY good, but the episodes with her drag it down. I hate tsunderes and find it really hard to enjoy a lot of anime series with tsundere main characters, but Kirino is extra obnoxious and makes it even harder. She's my second least favorite tsundere, right behind Haruhi.
7. Arata Kangatari - The first episode was really stupid so I was worried I'd dislike this, but it isn't so bad. It has some interesting moments to keep me entertained.
8. Date A Live - It's not very good, but it does manage to keep me entertained for the most part. It has some funny moments that make me laugh.
9. Photokano - "We shall take pictures of girls boobies and pantsu and call ourselves a photography club" Just lol...
10. RDG: Red Data Girl - It had a nice concept, but it makes little to no sense. The plot just jumps around from one thing to another and doesn't really do much to explain the developments at all. I know of a lot of people having a hard time following the storyline besides me too.
11. Aku no Hana - Possibly the worst anime adaption I have ever seen. I watch it simply so I can piss myself laughing at how bad it is.
EDIT: For some reason my post ended up all URLy.
