On the one hand, I didn't hate it as much as I was expecting to. I'm not a manga reader so I can't say how well they adapted the Conviction arc but story wise, it was okay. It was cool to have some levity after how fucking dark the Golden Age arc ended up, and I ended up really liking the side characters introduced here. I also watched the dub and again, while I would have loved for the original cast to come back, I think the replacement actors here did a pretty good job overall. And like I said before, I really like the OP to the series.
Positives out of the way, this was a train-wreck right down to the storyboard level. The way scenes were framed, the choreography of fight scenes, the lack of any sense of scale. Everything about this production came off as amateurish, something I'd expect and be more forgiving of if it was a web series like RWBY or Death Battle.
And all of that doesn't even go into the animation. Like, my God. I have no issue with the series being CGI. CGI animated series can be done well with the right direction but it felt like here that someone during production was unwilling to make a compromise. Shows like Star Wars Rebels (and Clone Wars before it) and Nick's TMNT prove that you can do fluid fight scenes and expressive characters in CG, but they also went with more stylized character designs to better fit the medium. Here, they tried to be as hyper-detailed as the art from the manga to an absolute fault, and when you add the poor direction on top of that, it ended in this mess of a series.
