Space Camp is a pretty decent film. The plot is predictable, but the actors do a good job, and the special effects are decent for the time.
This film was originally released about the time of the shuttle disaster, and that really put a hamper on how popular it was.
The scene where the shuttle doors open in space is simply spectacular... on the big screen, that is... on a TV... it just looks average. I remember this scene in the theater. It made you feel like you were really up there.
This would be a good film to see on IMAX, but I'm sure that will never happen.
