This sci-fi adventure is not the best and by no means the worst. I agree with the statement that bad sci-fi is comical. Bizarre pink tinting and unusual special effects make this a favorite for the late, late, late show viewers. Space explorers on the planet Mars fight off strange giant amoeba-like monsters and other strange creatures. Pretty cool.The cast includes Les Tremayne, Naura Hayden, Gerald Mohr and Jack Kruschen. Get comfy and enjoy. Don't feel bad if you nod off for a moment. I agree with adding this to the list of cult classics to not miss.
