What piece(s) of pop media have you not consumed that people would think you weird for not having consumed yet?
Just as examples:
I've never played a Pokemon game despite being just the right age where my peers were really into gen 1 as a kid.
I have yet to watch any of the Alien or Predator franchise movies (except Prometheus, which I didn't realize was in the Alien franchise when I watched it long ago) but am planning on rectifying that when I can get a chance.
I got my nerd card revoked after a convention when I revealed that I hadn't seen any of the Marvel movies. And this was about 10 years ago. I eventually made exceptions for Deadpool and GotG.
Wot!? Dude!! I started playing DnD just to get the nerd card and this is how I find out I still don't qualify??? I've watched X-Men (2000) though, does that count?
