First, this rating is meant to measure it’s worth as a film. If I were rating this for my admittedly base purpose for watching it - the sheer fun of consuming popcorn, wine, and heckling the actors while “sheltering in place” on a cold Sunday afternoon - then it’s a five. According to the details, it took nine days to make and $200,000. My kind of heckle-fest. These actors barely convince you that your TV is on. Two of them were very successful radio actors, Gerald Mohr, and Jack Krushin. The other two are unknown to me. Believing that these four could have landed jobs in maintenance at any kind of Space agency is a stretch. Scientists? Right. Each one has been given a standard character type left over from WWII era B movies and radio and each of them heroically underperforms. Chin whiskers and a pipe equals a “professor” sublimely unaware of anything remotely scientific. Krushin’s tiresome comic relief, honed in radio and useless on the screen, including a troubling relationship with a ray gun of some sort that he’s personalized as a woman, mercifully ends when he’s consumed by a giant amoeba. For reasons entirely understandable, this demise draws less emotional reactions from his fellow crew members than any of the silly blinking lights on the fake control board. Mohr moves about on exploration visits with an apparently loaded 45, finger on trigger, waving it in the direction of his fellow crew members like maybe it’s a flashlight or something non-lethal. (Was that actually in the script?). Dr. “Irish” Ryan demonstrates her bona fides as a scientist by playing, quite literally, with beakers and test tubes. The “rocket” interior is an office with a few faux tech pieces of nonsense. Gravity rules, if not in the script and performances, then in the office. You can stroll around, shave with an electric razor, and, most memorably, smoke a pipe right next to the high-tech sensor indicating oxygen consumption at just two levels - normal and excessive. Like the idiot military authorities on Earth, everyone believes that the best possible way of confronting danger or the unknown is to charge right out into it and see what happens. Accordingly, they learn absolutely nothing from their failures, an endearing quality in a scientist. Finally, there is the booming, echoing Martian voice bidding us to stay away. He’s better understood as a viewer warning you not to waste your time and money. Since it’s free on Prime, and since you need some diversion while sheltering in place, I’d ignore him.
