Breja: To me that sounds like a contradiction :D
Mafwek: Oh, I am just teasing;)
But while quality is subjective, new 40K content in recent years was well received by fans. New Star Wars films... less so.
Mandalorian is allegedly okay, but I have sworn never to watch new Star Wars stuff after the Force Awakens, so I don't know:D
You missed out on Rogue One, easily the best SW movie since the original trilogy. And even Solo i found to be a fun little adventure, even if entirely unnecessary. Mandalorian is ok (2nd season far better than the mediocre first). And the animated Rebels series also has some really great moments (it would be a genuinely great series if not for the filler episoeds in between the actual story arc stuff). Overall SW has really not been doing as badly under Disney as the popular opinion says (there's even been some pretty good stuff in novels and comics), it's just that the sequel trilogy (and the material immediately connected to it) is crap, and that's the flagship so it colors the whole perception.
As for 40k, I don't really have issues with the quality of any of it. It's just that the grimdark edginess of the setting is precisely what I don't like. It's all a bit too much for me, it always feels like something for teenagers trying way too hard. But I don't "hate it", and if there's a really fun game out there using the license, I'm still open to trying it. I've got Dakka Squadron on my wishlist, cause it looks like some good dumb fun :D
