Early clues that this movie will be a complete waste of time: Gratuitous female nudity before the opening credits are over, and wobbly cameras zooming in at screeching people to simulate predator attacks. And oh look, boobs were bared again 10 minutes into the movie.
Essentially this movie is similar in plot to the recent Ghost Ship - the crew of a boat find a (haunted) abandoned ship and board it. This script is crap, however. There's something about an Aztec curse, which leads to flashbacks of sacrificial rituals, which naturally requires there to be naked women. Despite the title, this is actually a monster flick. Effects are limited here (read: a monster that looks like a puppet), as is the acting. There are a few more experienced actors, and there are the actors that need a few more years of acting school before they can take up roles like "Bystander #1".
I wonder what a renowned actor like James Brolin is doing in this movie. I guess before he married money... I mean Barbra Streisand, he had to find some way of paying the bills.
