Lem is just an average teenager working on getting the girl and furthering his career at the local planetarium - except that he's an alien. At least to U.S. astronaut Captain Charles T. Baker who lands on Lem's planet hoping for a quick flag plant and a hasty return to earth and his millions of screaming fans. But on this alien planet the media has tagged spacemen as brain-eating, zombie-creating monsters, causing Baker to run for his life and into Lem's house. Now it's up to the green native to get the clumsy astronaut back to his spaceship before military dictator General Grawl and mad scientist Professor Kipple manage to exterminate the Earthly visitor. Written by The Massie Twins

Didn't quite match expectations, but a fun watch
22 November 2009 | by (Redondo Beach, CA) – See all my reviews

It's an "ET-in-reverse" story. An Earthling astronaut gets stuck on what he calls an alien planet. The local green folks call him (accurately) the alien. The story is a fond tribute to drive-in's, space-creatures sci-fi, and the 50's. With the Area 51 reference in its title, you know the film will be poking fun at everything it can get its hands on, including itself. It delivers this.

There's hover craft that look like big-finned autos of that era, black & white TV, and pioneer rock 'n' roll. It's clever humor, although some of this has been done before. There's a lot of parallels to Monsters vs. Aliens, too, in that frequent references to classic sci-fi flicks (up to the present, not just the 50's) pop up in sight gags and one-liner jokes. My fav was the character that resembled the Aliens movie creatures. There are other clichés sent up for satire: a loud mouth hawkish general, a wanna-be scientist, etc. Adults won't be bored thanks to these in-jokes, and the kids should like the slapstick stuff.

The film boasts a great idea, and some, but not all, of the potential is utilized. It's good natured and fun, rating about average for an animated feature.
