Personally, I hate that movie!!! It's so boring!! It's worse than SAW III
The movie starts off with a group of people (including the main character) hunting a boar and the conflict occurs when the Mayans capture their village and take them as captives to sacrifice them to the sun god. Fortunately when the main character is about to be sacrificed, an eclipse occurs and the Mayans think that the sun god forgave them. And the rest is about how the main character escapes from the Mayans and saves his wife and kids.
The climax is messed up! and the whole movie is so boring, at one point I thought of walking out of the theatre.
I learned a new lesson, never go to a movie without reading the plot or a review! I thought it was about archealogy!!
