This was so bad I can't even tell you what happened after people fell into the well, looking for some ... well, ruins, I guess. The acting was so terrible and the lines so non-digestible that I was distracted by other things for the 25 minutes or so I could stay with the film. Dumb teenagers? Check. Beer? Check. Sexual innuendo? Check. Getting slashed up in bed? No, that's another movie.
I think if you are interested in Mayan ruins or archaelogy, your best bet for a film on this subject might be a National Geographic documentary.
