The Lost Skeleton of Cadavra...
Naturally, I ran right out and rented it.
The movie was filmed in the style of the campy Sci-Fi B-movies of the 1950s and 1960s. It's in black-and-white, the dialog is bad, the acting is bad, the plot is bad, the science is bad, and the special effects are atrocious.
See, it's entirely possible to watch this movie and NOT KNOW you're seeing parody. They nailed their subject matter so closely, that the movie MIGHT AS WELL BE a campy, Sci-Fi B-movie shot in 1962. That fact alone ensures that this movie will never be generally accessible.
If they had it to do over, they should shorten the film by 15 minutes (easy) and then wrapper it with 30 minutes of "mockumentary" in full-color. They could then do to B-movies what Spinal Tap did to Rock & Roll films.
Should you rent it? Not if you're going to watch it by yourself. You need to surround yourself with geeky friends, and do your own "Mystery Science Theater 3000"-style voice-overs with it. That may be the best party game ever, or your video party may fall flat on its face.
Sandra and I watched it together. It got pretty stale in spots, but there were laugh-out-loud funny moments, too. And the gag reel on the DVD was like dessert -- you have to eat dinner first, but then the dessert is the best part.
