This is a short doc about the crystal cave that was discovered in Mexico around 2000. Miners for silver and lead, tapped into a flooded cave full of massive crystals. The crystals have been growing to massive sizes for over 400,000 years, and they are amazing! The only problem? Thanks to a magma chamber, deep under the Earth, the cave is too hot for humans. Special suits were designed for the scientists, and even with them, people can only stay in the cave for twenty minutes at a time. NASA scientist, Dr. Chris McKay, who studies extremophiles, was on hand trying to find life in the crystal cave. He also studies off world life, and how it would develop in hostile environments. The crystal cave is a perfect place to study these types of biosystems. The cave can only be studied for a short time, because by pumping the water out of it, the crystals stopped growing. It also weakened them, and put them at risk for collapse. This documentary was a brief, but beautiful glimpse into one of Earth's wonders.

So.....much......repetition!!!

It feels like the narrator tells us the cave's heat is deadly about a hundred times. Is twenty or thirty times not enough? Two explorers go to a crevasse seen two years ago to see where it leads - the narrator tells us where they are going thirty or forty times - or it seems that way - I didn't actually count.

This film has great content rendered nearly unwatchable by awful editing. I don't mean the cuts are bad. I mean the narration is absurdly, annoyingly, massively repetitive (but I repeat myself).

The film doesn't need to be shorter. There's plenty to see and explore. They just didn't write enough for the narrator to say so he keeps saying the same thing over and over.
