Bubba Ho-tep

What would it be like to be Elvis hiding out in an old folks home, particularly when there's a horrible conspiracy going on? Bubba Ho-tep takes one tab at answering that question. I thought the pacing was kind of draggy but the interplay between Ossie Davis and Bruce Campbell as deranged (or at least partly deranged) old geezers was fantastic.
Overall, I'd give the movie a B.
