Never read/watched Harry Potter (and some other trendy stuff)

Anybody here miss out on some trends/band wagons ? Even though it's something i grew up with, Harry Potter never really took off with me, don't get me wrong its cool and all but i never bothered to read the books or even watch the movies properly. I've only seen a few occasionally if it was at a school viewing or something. Same thing with Star Wars, was never really interested. Final Fantasy, i've heard its a great game especially #7 but haven't played any of them, Game of Thrones not even once. Feel like i've missed out and was wondering if i should maybe slowly check out some of these big titles. I'm just not a fan of following something because its simply trendy. I remember in High school everyone talking about either the Walking dead of Game or Thrones, it was kind of annoying tbh...
