Absolutely the worst movie.

I cannot think of one single thing that I would change about this film. The acting is incomparable, the directing deft, and the writing poignantly brilliant.

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

There is, somehow, an interesting story here, as well as some good acting. There are also some good scenes

Low budget is not a curse untill it meets low scriptwriting, confusing shooting and editing, hilarious dialogues, sound probably recorded on Nokia 3310 and... well THAT acting. Actually this movie is quiet a masterpiece. You can show it to a film school students as an example how do NOT make movies.

A lot of awkward cut aways and edits in this movie. the "monsters" in this movie was the same scene in the dark that flashes on screen for 2 seconds. The acting felt forced and there was a lot of conveniences to the plot, example, oh random Jungle dweller ready to kill the team? LUCKILY one of our team members knows the guy and is in his debt. or when they find the "tombs" someone just so happens to turn the shiney skull the right way to unlock them... ALSO something that really pissed me off... was the Professor guy at the end was like "you have to kill them all, A BULLET TO THE HEAD will do it, but be careful they will look just like us, you will be able to recognize them from their snake eyes..." HOW DO YOU KNOW ALL THAT?? seriously how... does his research say that bullets work on these things???... and why would that work if back then in ancient Mayan times there were no guns.. that part did not make sense at all.

This is one of the worst movies I have watched in quite a while. Story line is terrible and so is the acting. There is no continuity in the story. Things happen for no reason and the story jumps in time. The ending was horrible. If you have time to kill and you enjoy terrible films, then this is for you. Otherwise, stay away from this junk.

First clue that this wasn't going to be a good one was the intro-sequence that took 10 mins...To be fair - I thoroughly enjoyed how the cast switched from English to Spanish to Mayan (or something made up ?) seamlessly. No extraordinary accents, nothing so thick you couldn't make it out. Just a bunch of actors with great language skills !When 4/5 of the movie has gone by the diving and action starts taking place...the CGI and effects were effective and surprisingly good but not enough to save the movie....SPOILER ALERT Also an extreme logical blunder that really ruined it for me. WHY is it necessary to hold on to a timed explosive device to "fight them off as long as possible" ? Set it and forget it - run you fool ! Or in this case - swim.Also - why collapse the walls and stuff when 3-4 of the aliens ALREADY has pass you by and you just MIGHT NEED to know more about the containment devices used ??? Seriously - some scriptwriter was sleeping during class and when writing the script...ruined even more of the movie for me.Gave it a 2-star because of the actors doing a good job...perhaps even great given the material - hope to see more of them later !
