I've often talked about combining Romantic Comedy and Horror in some sort of parody combination amazing epic story. I just watched Tucker and Dale versus Evil and it was great!
I didn't like the blurb or description said they were backwoods because while not super bright the leads were just good old country boys.

The movie is awesome and Tucker and Dale are hilarious as misunderstood country boys. A group of self-involved teenagers think they're just backwoods killers, but it's all a misunderstanding and there's a love story!!

It's on NetFlix, you should watch it!
