`Bubba Ho-Tep' is something of a comedy, a little fantasy, and a horror film all rolled into one. The misadventures of a superannuated Elvis in a Texas nursing home are amusing, if not terribly funny. The horror part just doesn't match what we've come to expect from our horror pictures. The monster is funny in his cowboy hat and Texas boots, but not particularly horrifying. Ossie Davis is wonderful as `John F. Kennedy,' his paranoia forming the engine that pulls the plot forward. I got a somewhat pleasant kick out of `Bubba Ho-Tep', but I had been led to expect more than was there. So, an entertainer, but definitely a one-watch flick.
