There's no danger of giving the plot away, because anyone who has seen many movies will know from the first five minutes what will happen and who will die.
Saw it Sunday. The short version of what I posted in another thread is:
You know all those expedition gone bad movies with the hard as nails, cold, respected but unloved leader who dies nobly, the leader's vaguely other nationality right hand man who, of course, dies, the wealthy sponsor who is a smartass ******* who turns coward and leaves the others to die and who then dies himself, and the usual standard crew of silly girlfriends and helpers (who all, of course, die)? Well, this is another one. From the first moment you learned that the leader's son disliked his father, if you didn't know there would come the heartwarming moment of renewed love between them, you haven't see enough formula movies.
Not fun. Not interesting. Should have, as one reviewer said, just gone diving instead and waited for the DVD. (The trailer for Cowboys and Aliens was good, though. How do you resist that premise?)
