I'm not a huge fan of newer movies.
I know exactly what you mean. When I was a kid, I could watch any movie. Now, as I head into my late forties, I can't watch a movie unless I have MAJOR interest in seeing it. And half the time, I end up not liking it anyway. ("Superman v Batman", Suicide Squad, etc.)
I've enjoyed MST3K (brand new eps. coming soon on Netflix) and Rifftrax for quite a while. If I had to pick my favorite Rifftrax, it would have to be Battlefield Earth. I don't remember a damn thing about the movie or the riffs, but I do remember that I laughed harder and more often than during any other Rifftrax film.
