I mean it's okay to watch everything when you are growing up but after a certain point, one should eliminate the bad and keep the good. I've seen people watching the same stuff for years. His or her choice of course but you don't get to learn anything from those, when they are basically feeding off the same stuff. I thought the idea is to evolve as we grow up and not get stuck to mundane stuff.
I do not watch movies with a fixed agenda. I just watch them as to relax or just to pass time. So, I dont actually seek to 'learn' anything too. If I learn anything, then well and good.
If you call this immature, then I dont know what to say.
