Horror Challenge #94: "Unknown Origin"

This movie is basically a ripoff of John Carpenter's "The Thing."  It's about a submarine crew who answer a distress call to a ship where most of the crew are dead and the ones left don't speak English.  They come abord the rescue ship, but they're bringing a guest: an alien life form that wants to take over human bodies and gain control of the earth.  Our crew starts getting picked off one by one and eventually they have to figure out who is infected with the alien life form (because they won't listen to me yelling at the screen telling them who is infected).  The special effects aren't that great, but once the action started getting going, I was at least interested to see what happened next, so it wasn't terrible.  Nothing to write home about, though.
