It may seem a little bit of a copycat movie version of a certain TV series that others have mentioned in previous reviews, and yes, the theory is similar and that's where it really works. Viewers love the outdoor reality shows on TV these days and this movie takes the survival reality, to the next level. I can't say much about the plot but it will play out a little bit "obviously" throughout the movie, but don't let that turn you off, it has plenty of mystery and intrigue to keep the viewer switched on... just enjoy, as its a pretty entertaining movie..Chris Diamantopoulos was excellent in the role and upon doing a bit more research on him, as I hadn't heard of him before, I was surprised to find he hasn't had many lead character movie roles at all...a pity as would like to see him cast in a few more movies.
