I still like Spiderman, Harry Potter, LOTR, and Star Wars type movies, but most of what is out today is just inane and worthless.
Not to mention politically correct. Often it isn't the gratuitous sex & violence that bothers me, but the ideas. They're incredibly liberal and distorted. Also, I've seen some very weak plots.
I've been feeling alienated from Hollywood for quite some time. Maybe, as you said, age has something to do with it. I might be outgrowing movies. And I have better things to do with my time, anyway.
Two recent examples come to my mind, I. Robot and Van Helsing. Two of the dumbest movies in recent memory I ever saw. If it weren't for the special effects, both movies wouldn't be worth anyone's time or money.
