Other than the obvious "stranded aliens on earth" bit the 2 are nothing alike.

SPOILER ALERT!! DONT READ ANYMORE IF YOU DONT WANT TO KNOW DETAILS ABOUT THE MOVIE!!















This batch of aliens has no intentions on stopping here but they run out of fuel. They are able to make more fuel out of whats on the ship but it takes 20 years to produce it. They sit quietly in their ship when the humans decide to cut their way into the ship. They find emaciated aliens and they begin a good will campaign that turns into a nightmare much like any other refugee camp. Google "south african refugee camp" and you will understand the irony/similarity to real life.

An evil greedy corporation exists that intends on reverse engineering the alien weapons but they are bio specific meaning only the aliens can fire the weapons. The humans are essentially keeping them here and keeping them locked in their camp where they live like animals.

If your a science fiction fan you will love it.
