I remember Batman and Star Wars being the cool "in" things with kids in the early 90s. Batman was cool up until Batman and Robin came out. There were a few years where Star Trek was pretty cool and sold a lot of toys and such.
In fact I remember being a Star Trek and Doctor Who fan got me bullied by other kids who were Star Wars and Power Rangers fans. It was okay to be a Star Wars or Power Rangers fan but not a Doctor Who fan. I knew people who up until a few years ago wouldn't even admit they had seen Doctor Who,and most of the people who would pick on us were Star Wars fans,despite the fact that I was a Star Wars fan too!
I have never been picked on for being a Star Wars fan and even the non sci-fi fans I hang out with like Star Wars. In fact Star Wars is the only Sci-Fi I can think of that it has always been okay to like.
