Oh, I'm not criticizing Shock Waves... I mean, these guys, in SS unis, with goggle-style glasses, some of them, well they just.... lay there, in this swamp... and they must have had to just get in the water, then sink down and lay in the mud, looking mindless, and then stand up and walk towards people, who scream and run, or shoot them , but it does no good... and it is, as Victoria says, pretty creepy. It's much creepier than Alien Cargo, which is about some 'space junk' brought aboard a freighter spaceship, which turns out to be blue goop, which we don't see for a long time - goop that turns out to be inside an ancient NASA probe of some kind, that... well it causes bad things to happen, and at the end we might learn what the bio-goop is, but No, I can't remember, because of the sadness of the ending, where our couple just floats away in the ship, no air left, because they are infected and don't want to kill us all by coming back to Earth.
