Once in a while a film comes along where the one-line description just makes you want to declare it a work of genius. Snakes on a Plane pretty much wrapped that up in the title. Bubba Ho-Tep is in the same realm. Here's the one liner for Bubba Ho-Tep:
"Elvis and JFK battle an undead Egyptian mummy in a Texas rest home."
That's all you need to know. Either that movie sounds like genius to you or it doesn't. I happen to be one of the people who thinks that sounds like genius.
The end result is a mostly great movie. It's definitely a cult classic, and of course casting Bruce Campbell as Elvis didn't hurt its chances for that. I think the middle drags a little bit. I might have enjoyed the JFK aspect more if the actor playing JFK had had a Kennedyesque accent (think Mayor Quimby). All around though, the movie is a good entry into the Horror-Comedy genre (Evil Dead 2, Army of Darkness, Lost Boys, etc). The first 20 minutes are especially funny.
Rating: Great/Bad movie. I saw it on Comcast's fear.net channel, but I'll be buying the DVD shortly.
