Elvis and JFK did not die, and today they're roommates in an East Texas nursing home whose residents are being killed by an ancient Egyptian Soul Sucker named Bubba Ho-Tep. I want to get that on the table right at the get-go, so I can deal with the delightful wackiness of this movie, which is endearing and vulgar in about the right proportion. The movie doesn't exactly work, but sometimes when a car won't start, it's still fun to look at the little honey gleaming in the driveway.
