from RiffTrax:
Paranormal Activity succeeds by putting the viewer in the most deviously terrifying position ever imagined by a filmmaker: captive audience to an idiot’s home movie. It recreates the experience of being stuck in a room with Micah (pronounced MEEK-uh, or DOOSH-bag), the kind of guy you immediately want to start punching and never stop punching until the punching is done. The kind of guy who spends his free time at the mall, conspicuously checking out 16-year-olds while chatting loudly on his Bluetooth headset about hair gels. In short, Micah is a super sweet dude.
Get it here.
