Super has shaped up poorly in my opinion. The retread of the movies was exhausting enough, but the Universe 6 tournament has been a bit of a slap in the face. The first few episodes of the current arc were pretty solid. We got interesting concepts and interactions...and as of the last couple episodes, it has completely fallen on its face.
I am a pretty obsessive fan when it comes to Dragon Ball, and even I can't stick by Super. If the next episode is another disappointment, I think I'm going to jump ship entirely.
To the point of the animation, yeah it's been pretty subpar on average. There's some good stuff in there, but it's been extremely rare. And the noticeably-bad is far too frequent. To my understanding, a huge part of the problem is the current state of the anime industry: They're producing more content than ever, with roughly the same number of people and a higher proportion of amateurs. In that state, the quality is going to suffer. The infamous fifth episode of Super (the episode those images a few posts up come from) also had the misfortune of scheduling problems. Some of those frames were redrawn for the blu-ray release but on the whole, didn't result in a huge improvement.
But I'd be remiss if I didn't point out that the original animes had pretty varied quality too (though still with a better average track record). Pretty much anything done by Last House after the Freeza saga has atrocious artwork and passable animation at best:
Studio Live's work wasn't much better:
This isn't to say we shouldn't criticize Super's quality. Criticism is one of the most important things in art. I just thought it would be interesting.
