Totally dud and irritating early 80's monster crap that righteously would be forgotten already, if it weren't for the fact that superstar Demi Moore experienced her very first leading role here. It's often interesting to find out about the tiny low-budget productions that introduced big stars to the movie industry, but this thing is a catastrophe and it's actually a miracle that Demi Moore ever made it to the top if you see her painfully bad & amateurish performance in "Parasite". She's not just bad, she really sucks and her only consolation is that everyone and everything else sucked, too! The script is boring and filled with annoying clichés, Charles Band completely forgot to add suspense and the contemporary very popular 3-D special effects are truly childish. The events in "Parasite" supposedly take place after a nation-wide disaster, and I usually LOVE that, but director Band completely fails to illustrate an eerie apocalyptic ambiance. The populations in towns has decreased to less than 50 and you have to pay a fortune for a fresh piece of fruit, but there are no other things that indicate we're in a hopeless future. The sole scientist Paul Dean, with a parasite monster developing in his stomach, flees to a godforsaken desert town to work on a cure. There's a cruel government agent following him, and even the local imbeciles don't leave him in peace, as they steal his equipment and infect themselves with flesh-eating parasites. Those idiots! I'd like to name one (just ONE) amusing sequence or ingenious element to be not entirely negative, but I really can't think of anything. Even Stan Winston's creature designs are lousy. Skip it, people.
