This was on the same DVD as THE INCREDIBLE SHRINKING MAN and I actually liked it better. It's definitely an original idea: a meteor crashes in the desert and explodes into a million pieces. When the pieces get wet they start growing and growing until they turn into giant towers and fall over exploding into a thousand pieces and all of those pieces do the same thing. Also if you happen to touch one of the rocks that's gotten wet it'll suck all of the moisture out of your body and turn you into rock! Yikes!
For a B level sci-fi thriller this was a pretty fun movie. The acting is over the top and the music is way too dramatic, but that's what makes it so much fun. If you like 50's sci-fi then you definitely need to check out THE MONOLITH MONSTERS. My biggest complaint is not enough people turned into stone.
