Lots of nice looking anime coming out this summer.
Definitely going to watch Zankyou no Terror. The Watanabe/Kanno tandem never disappoints.
Will try Aldnoah Zero. Urobutcher is usually hit or miss but Gaim is going great. He might keep up the pace here.
Don't know if I'll watch Free Season 2. I think Season 1 already gave it a conclusion but who knows.
I'm not sure about Space Dandy Season 2 too. It's from Watanabe too but I think that's he's weakest work. Don't know if Season 2 will get better.
Shirogane no Ishi Argevollen, Tokyo Ghoul, and Ao Haru Ride all look interesting. Might give them a try.
