This has been a really great season so far. There are a lot of good shows, including a few surprises. Here's the new stuff I'm watching. Not counting carry-overs from last season (like Blast of Tempest, go watch it) here.
Maoyu - I continue to dislike the character designs but despite the addition of random unnecessary fanservice for the anime, the core of the story hasn't been changed and the show is quite good. All the macroeconomics and farmer methodology I was hoping for. It's a shame that the producers were afraid to make an intelligent show without having the fanservice to fall back on, because it just feels incredibly out of place. But at least there isn't actually very much of it (past the first ep anyway).
Kotoura-san - Agree with the sentiment around here. I was hooked from the first episode. Very interesting show, with a mix of comedic and serious elements.
Oreshura - No, seriously, this show is way better than I thought it would be. Not that I thought it would be very good, mind you, and I still wouldn't exactly call it a classic or anything but it's quite entertaining for what it is. A harem comedy with actual character development? Who would have thought.
There are also a whole lot of sequel series this season. A few that I'm watching:
Chihayafuru 2 - Loved the first season, so naturally I'm enjoying this one.
Minami-ke - More Minami-ke is always a good thing.
Haganai NEXT - Can be a bit over-the-top, but I enjoy the silly slice-of-life-esque comedy with wacky characters.
I'm dropping Robotics;Notes, though, because it really feels like it's going nowhere and it has much tougher competition this season than it did last. It's a shame that it just doesn't hold a candle to Steins;Gate.
Of course there's still stuff continuing from last season, like Blast of Tempest and Psycho-Pass. But it still looks like Maoyu will be my favorite show of the season since things have really slowed down in Blast of Tempest (though they kind of had do, it's actually nice to have a break after the amount of tension in the first half...).
