You found Sebby!

What can I say? It was pretty bad. The general storyline is quite predictable, most of it was shown in the trailers.

1) Crew crashes into desert
2) Can't walk out
3) Limited food
4) Builds a plane (in trailer)
5) Escapes the desert

In the meantime, there's only once whereby nomads actually attacked them.

Count the stars. Watch at your own risk...
