Airing:
Tokyo Ghoul - I'm loving it so far, I haven't read the manga. But people have said that they skipped an arc from the manga.
Akame Ga Kill - It's a run of the milll shounen, but it's pretty entertaining.
Zankyou no Terror - 10/10 for now. Even annoying MC girl got a little better in my book after the last episode.
Aldnoah.Zero - Best MC. Looks great and BEST OST this season.
JoJo's Bizarre Adventure Stardust Crusaders - Not as strong as Part 2, well for now. But I am still loving it, great series.
Not Airing:
Shingeki no Kyojin - When it first started airing I watched it. Liked it at first, but felt like it started to become slow. So I stopped watching it at around episode 8. I really do not enjoy it, but I started watching it again because I started watching anime with my mom. I've heard that it made many people that haven't watched anime, start doing so. For me it's still meh, but my mom is loving it.
Log Horizon - I am on episode 15( dropped it before) and I'm trying to start it again. Overall the series is great with interesting ability system. Also there are many likeable characters.
Accel World - Also had it dropped. My only complaint about the series is the MC. Even his damn model/art style is completely different compared to every other character in that world.
Hataraku Maō-sama - Nice, funny series. I feel like some things happened too fast. But overall it's enjoyable.
Neon Genesis Evangelion - As I've heard this series is either loved or hated. I was lucky enough to go in blindky into the series(Spoiler! Except that the MC is not super, hyper over the top like most MC of Mecha shows and the ehhh self pleasuring scene). So far (episode 3) it's great. For the first time ever I actually feel sorry(unlike the MC in Mirai Nikki and Accel World) for a MC who is scared/spineless.
Blood Lad - I don't even know what, but something is missing in this show. I am in the middle of it and simply feels like somthing is missing. I don't even want to finish it anymore.
