If you even hit play on this film, you know what you're getting into. It's corny, bad acting, horrible plot, the usual B film about Mayan "noble savages." Weird combination of facts and new age theories as one other user mentioned. Good option if you know you're going to fall asleep, and if you manage to stay awake it's at least "so bad it's good"-ish.

Not much action. Not much horror. Not much suspense. Some interesting locations, but the movie is slow, the plot weak, characters shallow. Minimal background and history. An hour in, little had happened. As another reviewer mentioned, they're supposed to be top expert divers. They don't use rebreathers. I was uncomfortable listening to them jabber in underwater caves when one would be conserving air. It should have been silent with captivating underwater footage. The dialogue foreshadows what's to come. I wanted to be drawn in more than I was. I ended up just wondering if I wanted to see the end or not. All the suspense was in the last 20 minutes. Super cheesy. It got so ridiculous at the end, I couldn't take it. Just another greedy white man with no respect for the culture of others. Skip this and watch The Abyss!

As with most movies, the last twenty minutes are where the good stuff happens and things are wrapped up. In this case, the last twenty minutes got a bit confused. There was a definite conclusion and it seemed to fit the rest of the story, but it had more potential and it left a lot of questions unanswered.

Things got weird in a hurry and then sort of slipped into another movie.

In any event, the acting was pretty decent and nobody got too melodramatic until the last few minutes. The scary guys were a bit weird and overdone. The ultimate ending was a bit odd and there was no explanation as to why the other players couldn't do whatever by themselves.

If you can see it for free, it's not too bad.

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.

It's definitely a SyFy Channel wannabe, but actually with a far better plot and cinematography. The biggest con is it takes forever to truly get to the action with the "aliens". While the build up is decent it lacks energy. The direction and story building is there but the actors for the most part seem to just go through the actions. The fact that the build up takes so long and you invest in watching for a payoff the payoff comes slate and leaves the movie open as if this were a pilot or the beginning of a series of movies and with the premise used. Sadly, because of that the ending was empty as a standalone.
