Well, yeah, if you count movies like, from the 1990's and beyond, there are a ton I haven't seen and don't plan to. That goes for most of the superhero movies. I don't know, something just isn't compelling to me about seeing Hollywood actors dress up as heavily modified versions of characters I grew up loving. It's like a popstar covering all my favorite 80's metal tracks, or something. Plus, they just don't look that interesting to me.
But I mean, Titanic, Independence Day, countless moves from the past 30 years that were huge that I never saw, which are probably part of the pop culture fabric in many ways. I was sorta only thinking about awesome, classic movies when I saw the thread title (like The Warriors or They Live), I guess because this was Sherdog and it's a pretty macho place.
