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.
