There's a lot about horror that I like! I can go on and on about the genre, but I'll try to condense it as best I can. I'm not big on the superficial stuff like blood and guts, but here's what gets my ass in a seat!
-I love the mystery surrounding it. The idea of being guided through the dark unknown and not knowing what you'll see is a lot of fun!
-I like exploring those dark "what if" scenarios. 50% of what makes me interested in horror is the concept alone. If the concept grabs me, I'll likely read/watch it.
-I like seeing innocent, everyday people fighting against something stronger than them and rooting for them to come up on top. I'm not big on slashers where all the other characters are kill-fodder jack-asses because I want to root more for the everyday people instead of the monster. I know a lot of people like to watch slashers because they root for the monster, but I'm not one of those people.
-Dark humor, when done right, is so much fun! Tucker and Dale VS. Evil is a great example of that! Not only because of how likable the leads are, but it takes the "evil hillbilly slasher" sub-genre and turns it on its ear! The humor works so well because everything is happening due to accidents and misunderstandings, making the leads seem like the evil hillbillies they appear to be.
So, yeah. That's what I like. That's about as short as I can condense it.
