Marvel and Starwars have been taking heat for pumping out boring and poorly written films for a while now. I think Pixar's stuff is still mostly decent, though. That being said, I also expect a completely different standard of work from Pixar since it's for kids first and foremost.
That's fair, I think you're right that it's subjective. I think Disney managed to pretty much kill the main Star Wars movies at least for me. That said, we also got some pretty great stuff that we definitely wouldn't have gotten otherwise so it's not all bad. It was really sad to see LucasArts gutted and EA get exclusive rights to the license for a while though.
In exchange for 3 shitty movies, we did get a CRAPLOAD of other Star Wars stuff. Animated: final season of Clone Wars, 3 seasons of Bad Batch exploring immediate post-order-66, Rebels (Mother. Fucking. THRAWN), and more that I don't remember.
Several live action shows: Mandalorian, Kenobi, Ahsoka (MORE. Mother. Fucking. THRAWN), Book of Boba Fet, and more, I think, but again, I can't remember.
