Here come the aliens

Here are the greatest extraterrestrial visitations that have ever hit the big screen. Because not all encounters are created equal, we ranked them by CNET sister site Metacritic's Metascore. You're welcome.

For the record, yes, we know Superman and Thor are aliens. We're not including comic book movies in this roundup.
