I agree on your opinion about this anime season. I have only Ao no Exorcist S2 in my watchlist. (But I'll only watch this because I've watched the 1st season.)
Konsubarashi, youjo senki, Gundam: Iron Blood Oprhans season 2, Demi-Chan, and 3-gatsu no lion were all pretty good. Although only 3 of those were new this season and 2 were carry overs from the previous season.... As for next season Boku no Hero Academia season 2, and Shingeki no Kyojin season 2 should be good. I'm also going to give that king's avatar anime and the new berserk a chance along with the new shingeki no bahamut. Can't say anything else has really caught my interest but I'll wait for some reviews on the comedy and slice of life anime's coming out. I wish the how to pick up girls in a dungeon new anime was a season 2 instead of from the blonde girls POV. I'll probably check it out though.
