A bit late to party. Before I give my contribution, I have to commend
Li'l Lemmy for his effort. Honestly, I doubt it will matter much.
When the new arc shows any type of "weakness" the bashing will return in full force. And yes there's a difference between bashing and building a well formed criticism like this thread pretends, putting people into: "haters" and "white knight's" category is aggravating.
I was pretty disheartened with this part of the forum, when the negativism regarding the new arc was in full strength, people concluding it will suck because Black Goku is Tullece II, even without knowing anything about the arc and many more of this sort. I'm also including the unfortunately regular off-topic one liners. This forum become temporarily a place I didn't wanna be, which is sad since I hold it in very high esteem due to it's positive standards.
First I gotta say I'm very positive regarding it and it's continuous improvement even with the bad start. Ok, problems:
Lack of imagination/courage and relying on nostalgia:
Again and again the show has revisited various emblematic moments, instead of creating original content. Vegeta fight vs Magetta is one critical example, that Final Flash is a carbon copy from the Cell Arc.
Callbacks aren't bad, sometimes it can be very well done and highly enjoyable. This isn't the case here, there's an insistence on it which makes me think the writers are afraid of creating new content. Or prefer to play it safe and "recycle" the series since they know it works.
I hope the callbacks are far and spread apart. Let Super create it's own iconic moments!
Inconsistent and bad character portrayals:
Writer A the character acts this way, writer B it acts the opposite. I don't enjoy seeing character flip flop like this, in some causes there's barely an ounce of the true character as intended by Mr.Toriyama. Episode 42 is a case were Goku was awfully written, in this case to make a thin premise happen.
Contradictory Power information
I know some of you don't care about this but I do. I love the redundancy of putting a character a bit stronger than that one but weaker than the other guy, etc... Well, if I enjoy it, it's not redundant after all.
Super is creating inconsistencies at a ever growing rhythm, I liked them to at least build tiers that everyone could understand in wide strokes. It's the bare minimum.
There's a few other small/mid problems that I have, I won't prologue myself much longer or this post will become bigly(

). The awful scheduling, which resulted in bad animation has been apparently solved. It's not a problem anymore.
