Parody movies are like an art form. Done right, you get a cinematic equivalent of a van Gogh, something that is both funny and shines a light on some of the more ridiculous common threads in movies. Done wrong, you get the equivalent of a 5-year-old's drawing that's been stomped on with muddy shoes, put through a washer, and flushed down the toilet. I'll give you two guesses as to which of these categories I think A Haunted House falls into.
