Xibalba

The 2 cave divers you see diving in the real cave were diving with 2 side mount cylinders as well as a smaller cylinder (deco or bailout bottle) and were wearing normal scuba masks, one with helmet with 2 lights on the side (typical cave gear). Yet when you see ALL the divers come up, they are wearing full face masks, only have a single centre back mount tank. They also talk about being low on O2 (not air) and earlier discussed oxygen percentages they had left. It should have been how many PSI or Bar they had left. I'm sure they just took some stock footage of cave divers and put the rest in, but even non divers can tell the difference in gear.

Well, I found out that this movie was based on something with aliens and ancient Mayan lore, so I figured that it might actually have potential to be something worth watching.

Turns out that I was quite wrong. Wow, this movie was, and let me be bluntly honest here, god awful boring. There was literally nothing happening of any worth or interest happening throughout the entire movie, except for maybe the last five or ten minutes of the movie. And even that wasn't something you'd get worked up about.

This was essentially just following an expedition crew as they participated in what have to be the most boring expedition and spelunking ever.

The dialogue in the movie was fairly flaccid, but then again it did of course match the characters well enough, because the character gallery in this movie was just horrible. Every single character could essentially be replaced by a cardboard cutout - as they had the same personalities.

I will say that the creature - or more correctly - alien design was actually good, and that was the best part of the entire movie. But it was nowhere near enough for making up for all the rest of the movie, as it was one massive disappointing shortcoming.

Do no bother with spending your time, money or effort on this 2017 movie by director and writer Joaquin Rodriguez. Some of us suffered through this ordeal titled "Curse of the Mayans" (aka "Xibalba") so you don't have to.

I am rating this movie a generous two out of ten stars.

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!

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.

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.
