Sure, the special effects are cheesy, but they are hilarious! Hilarious = a "10" in my book. You have to look past the special effects in order to see the clever story behind them. An astronaut picks up a slimy splash of an unknown alien organism. He brings it back with him - unbeknownst that it's hitching a ride on his leg. The mucous develops into a tentacled creature that feeds on electricity and the whole ship is infested with these things! How I wish they would remake this film today. Good Story + State-of-the-Art special effects = a "10" for sure! Even on video, it's a hoot for the kids - pure, clean, and fast-paced fun! For the men in this crowd, the sheer presence of Luciana Paluzzi (bad girl in "Thunderball") is worth 4x the price of this gem!
