Cheesetastic, low-budget parodies of genre movies have been a staple of American multiplexes and direct-to-video releases since 2000, when the Wayans Brothers released Scary Movie on all of us. It was perhaps inevitable that a genre that was dedicated to pointing out the ridiculousness of American culture would succumb to that same absurdity: you can't take already goofy concepts and up the ante by juxtaposing them with other ridiculous concepts and maintain high levels of sophistication and good taste.
Maybe this one has a little more guts to it, if only because it takes a bit more courage to take on a wildly popular franchise that people take with dead seriousness than to make fun of movies that people go to see because they enjoy a jolt, a nervous laugh born out of momentary and easily dissectable fear. But it doesn't take a lot to make those juxtapositions, instead of to build something new, something cool, something profound, something lasting. These movies are the equivalent of poking a vampire gently in the shoulder with a stick, rather than staking it vigorously through the heart.
