A 10 you say?
No, it is not deserving of any Academy Awards, but it sure is fun to watch. C'mon, the film even makes fun of itself, "I voted for outer-space, no way these are local boys." But that's why it's a good time, a few grisly deaths, and you can just sit back and have some fun thinking about if these things could roam around the desert for real.
Okay, no.
The best scene is in the basement rec room, you know the one with the gun collection.
10/10
