I almost always start with mentioning the actors who were in a movie. With this film, 99% of everyone in it only have Apocalypto as a credit, so mentioning actors isn't much use.
The film focuses on Jaguar's Paw, a Mayan native living in the jungles of Central America around 1500 or so. His tribe is attacked and mostly captured and brought to a city nearby.
I don't know how accurate this portrays Mayan civilization, but taken as an action movie, there is little to fault it.
This is a high adrenalin movie and as with most Mel Gibson movies, there is no shying away from the brutal life of the time.
I liked it and recommended it to lots of my friends. It is worth the price of the ticket and a real roller coaster ride of a movie.
