Lots of fun in this underwater thriller as a team of scientists and miners battle a mind-controlling alien parasite that takes over their bodies. The thrills and the laughs never quit in this nifty micro-budget flick, that harkens back to the best of Roger Corman's drive-in classics from the 1960's. Clever writing and direction that overcome the low budget make this one a sure-fire bet for a fun evening in front of the TV.
