I think they're getting hyped up before they're released, and so we end up with really high standards. I haven't watched much this year, but 2014-2015 had a lot of painfully cliche characters, overused storylines, and over-the-top fanservice. Personal favorite of the year is probably Gakuen Handsome, because it parodies and represents everything that is wrong with anime. YOI started weak, and then get really good half-way though, continued to improve for a god 3-4 episodes, and then ended kinda.....I mean it was a pretty good ending, but the episodes before that felt a lot more emotional.
Animation quality hasn't improved too much, but they're trying out different styles which is cool. I'm guessing that they fix the frame rates, anatomy, etc. in the Blu-ray. If not, there wouldn't be much reason to get it lol.
