They tried. The story is good and they don't fall for specifics and science mumbo-jumbo. The cast was good and the scenery was too. Something simple to pass some time.
My problem with this movie is the girl. Why did she had to lie to him? There was really no reason for that. If you haven't seen -real- humans in a while, might as well make the most of it and gain their trust. I know that was supposed to be used to extend the drama of the movie, but c'mon; they could have done that with the side quest for helium, a quick look at the museum. All happy, now GTFO.
The was potentially, but the execution was not the best.
