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.
