Y'know, those things, tv shows, movies, fads that other people rave about, that you don't see the sense in, don't get excited about...what doesn't float your boat?
For me...it's Doctor Who and steampunk. The weird thing about both of those is that I am a confirmed science fiction fanatic. But Who leaves me scratching my head, and The Difference Engine, by two of my favorite writers, was sleep-inducing. I don't have any sort of fascination with the Victorian Age anyway, so maybe that's the hook I spat out. I dunno.
Doctor Who is just silly. I like Tom Baker though. Met him at ChiCon a couple of times. Cool guy. Good actor.
Oh, and zombies. Though I'm fascinated by the real thing, the powder, the serpent, and the rainbow, I don't get the Romero-inspired trendoid version. I think they're sparkly (and don't get me started about THAT.) I differentiate by spelling the stuff I'm interested in "zombi", like I call the stuff I like to read SF and not Sci-Fi.
How about you?
