Plot hole: Terl says that the army of humanity (presumably the U.S. Army) could only put up a nine minute fight against the Psychlos, and yet in the end of the film, a couple of outsiders, who taught themselves everything they know in just two weeks, can defeat their army. Why? The outsiders are outnumbered, they have had zero combat-experience, they use weapons that are over a thousand years old. That's just amazing.
