It has not been anywhere near as bad as ANAD or Now 2.0 and you can't tell me otherwise. The X line relaunched twice under Alonso. He left right as the third launch was happening.
We haven had an America yet, both in terms of quality or just sheer offensiveness. We had some outright bad or offensive books under Alonso and terrible PR for those books to boot and it has not been nearly that bad. "Some good books and some eh books" also describes DC right now at this exact moment as well.
Marvel has:
Immortal Hilk
Venom
Ms Marvel
Thor
Guardians of the Galaxy
The bulk of the X line
Iron Man is a mixed bag right now with it being a whole 2020 event, but it was high quality under Slott
Black Panther and Captain America, get mixed praises because Coates is a good writer, but maybe not the best superhero comics writer.
Avengers under Aaron has been average. Not even terrible.
The entire Spider line is good, yeah? I mean, everyone seems to largely think positively.
The problem is Marvel lost its momentum due to COVID.
Even if the books aren't screaming from the heavens right now for how amazing they are, Alonso's era was actively convincing people to drop Marvel because of how bad a huge chunk of it was and the consistently dumb shit he was saying, which has not happened with Cebulski. Plus, the few events that have happened under Cebulski: War of the Realms, Absolute Carnage, Contagion, No Road Home, and House of X/Powers of X, were all pretty solid to good. War of the Realms being the worst and even that wasn't that bad. Now we have Empyre and everyone here admitted a strong start and has been excited for it due to Ewing.
The biggest issues is somehow minimizing the Avengers brand, reupping the X Line and of course, David Gabriel still saying events and events on top of events.
It's still a long way out but honestly, it felt like he never left. Akirasan just got lucky Cates was the last Axel hire and still had a good team of writers, still mostly white guys and while the X Line is back up and running, it feels like it came at a cost. The Young Hero push just ended and we're about to do another event while the current event is just starting. Also, giving Slott F4 and Spencer ASM will likely be misfires if both runs end badly.
