It has low tier worth on a critical scale, though it's one of the few shit series that I actually find myself enjoying.
On it's positive side, the development of the secondary cast is quite good and it's entertaining to see that skill plays more of a factor in battle than it did in Z. Some of the new characters have OK designs too, I guess. It's plot lines are at least far less of a recycling of past ideas than GT was if you look at the first two arcs as honest remakes rather than the blatant ripoffs that all GT Arcs ended up being.
As for the wave of cons, for starters, there's the powerscaling being bullshit, as anyone can be as strong as anyone just because to the point it's almost as inconsistent as the silliness of post-Soul Society Bleach. In fact, many of the arcs are such trainwrecks in either using cheap plot devices or having a poor execution, such as being yet another series to jump on the bandwagon of the bane of good writing that are time resets and time travel paradoxes. The execution of the Future Trunks Arc's finale in particular was the lowest point of Super's writing, with an inconsistent power scale in the manga and a poor execution of the fight in the anime, coupled with a time reset ending.
Speaking of which, such fake tension is the main thing that makes Super a cashgrab. Being set at a point that has to lead to the events of the manga's finale (unless that's retconned), the entirety of the story has no tension due to prequel-syndrome, as we know the U7 characters will all survive one way or another. Even though they had cheap plot devices since the start, each arc still had enough tension in DB and Z with villains who would wipe out a large percentage of the cast and make things look hopeless. Now, it seems a miracle for there to be even one major casualty per arc for the U7 fighters.
Even the previous pro about characterization isn't perfect, as for many characters, Super just exaggerates single traits and turns them into one note characters. Chi Chi's always wanting Goten to study like Gohan and is usually mad at events going on, Roshi is always perverted and not as much of the wise master he once was, Boo is now a selfish glutton and most of all, Goku's naivete and lack of general intelligence is as overblown as it was in GT. Even the new cast have become more one note over time, such as Beerus seeming to not care about much other than food.
