It got a huge popularity boost, but they've always been pulpy popcorn flicks. Phase 5 was particularly bad in terms of writing but I think that's the only substantial difference from the earlier phases. I enjoyed a lot of Phase 4 (people are quick to write off the hype of things like Wandavision or Spider-Man No Way Home), and I'm glad I got the chance to watch some Phase 5 shows that might have otherwise been canceled.

It's just course correction from the pop culture explosion. Comics will continue to be weird.
