I like some horror movies, but the ones I like are few and far between... Same with romance movies or "chick flicks." Both of these genres of movies seem incredibly unrealistic to me. With romance, there's usually this love triangle thing going on, and then the woman is supposed to marry one guy, but the other one shows up at the wedding and then she suddenly realizes she wants the guy she wasn't originally going to marry. That kinda stuff doesn't happen too often as far as I'm aware. Beyond that, they're usually boring anyway.
As for horror, I can't get into them for partially the same reason: they're unrealistic, but even more so than romance movies. My brain analyzes stuff way too much for me to enjoy them usually. The Ring just made no sense to me. The Blair Witch Project just made me laugh my ass off. When I was a kid I appreciated the Friday the 13th series a bit, but that quickly ended due to the lack of realism. I mean, come on... Teenagers running thru the woods at top speed with Jason slowly walking after them... Then Jason magically appears in front of them... Whatever. My other issue with horror movies is the characters seem to be incredibly stupid. "Hey guys, there's a killer roaming around town. Let's split up, take showers, and have sex while all this is happening. GREAT IDEA, HUH?" A comedian named Pablo Francisco once said "you could strangle those kids with a cordless phone," and I feel that comment right there fits perfectly with how I feel about horror movies. Then there's ridiculous crap like "THE FOG." Oh no, not the fog. I'm so scared of FOG... The Hills Have Eyes: Not too terrible really, but that kid really pissed me off. He has a gun for most of the movie. He sees bad people doing bad things and gets scared and whatnot, but he doesn't take a single shot the whole time, EXCEPT when he's being chased, at which point he just wastefully blasts off rounds over his shoulder, missing every time. Almost every horror movie I've ever seen could have been ended in 5 minutes if someone would have just changed one little thing. I realize that wouldn't make for a good movie, but I don't feel that making people incredibly stupid just for the sake of making their situation worse/futile so it seems like they're in real danger makes for a good one either.
The only horror movies I really like are generally also comedic in some way(From Dusk Till Dawn, Sean of the Dead, Jeepers Creepers) because the fact that they're funny(at least to me) negates the fact that they're ridiculous and unrealistic. In fact, their ridiculousness is part of what makes them funny in the first place. The only exception to this is I used to like SAW(I appreciated it for the fact that it was a somewhat elaborate plot and not just some crazy guy with a mask and knife killing teenagers for no reason. It was different), but after seeing like 4 of them, I got sick of seeing people maimed in crazy contraptions. It just got old.
My favorite type of movies are comedy, war/action, and fantasy. I can appreciate Scifi too, but not so much when it's nothing but spacemen, robots, and aliens. That kind of stuff never really appealed to me. I have absolutely NO interest in Star Wars/Trek.
As for books, well I really don't read books at all. I used to love to read as a young child, but that ended when my school started having a hissy fit over the books I was reading. I used to read almost nothing but Garfield and Peanuts comics and those "Mr./Little Miss whatever" books(mr. happy, mr. grumpy, mr. sneeze, etc.). Apparently my teacher though I should have been reading Judy Blume/Beverly Cleary, so they made this stupid rule about how I had to take some kind of novel out of the library, and I was only allowed 1 garfield/peanuts book a week... So I just said screw it, if I can't read what I want, I won't read at all. The stuff they wanted me to read in school never appealed to me.
