Aliens will soon be descending on the western front in Cowboys & Aliens. In the movies, aliens have always come down to Earth to either greet us or eat us. Sometimes the aliens are a masterpiece of genetics and intelligence. Other times they are just dopey shmucks who just sort of wandered onto our planet accidentally. Hopefully when it happens for real, they’ll be the latter. We pulled up a list of the best and worst aliens, rated by their bad@ssery. Check out the gallery after the jump.
