I'm 48, and I asked the little missus if she wanted to see a movie the other day and when she said maybe I looked at the listings and didn't see anything I really wanted to see, except maybe the Mr. Rogers doc, which wasn't fitting the bill so we just didn't go.
Have seen some of the big action/superhero movies with my son. They are all (mostly) about equal fun...but genuinely good movies for an adult human? No. Which isn't to say it's gotten worse, at least not in my memory.
I'm hoping Sorry to Bother You gets a wider release next week, it looks interesting.
