So, I've been reflecting on Phase 4, and I think it's actually a very smart move.
No Avengers films. No HUGE event films.
I think, at this point, they can confidently make movies for a phase that aren't all billion dollar explosions at the box office. They can scale back a bit and focus on the characters, instead of the next big thing. They might lose some people, but I'd rather they focus on quality than playing directly to fans who just want big big BIG events and risking lowering quality to meet that.
So I'm happy with Phase 4. I'm sure Phase 5 will have some more big names in it, such as Black Panther, Guardians, etc.
