I saw this movie and while it wasn't really too bad for this genre, I had problems believing a few things:
1: The main character is a very good caving expert but they go into this very "perilous" caved in mine with out basic safety gear like helmets.
2: After 58 years, the power is still on in the mine and the lights still work. This was lucky because nobody seemed to be carrying any torches or lights.
3: After 58 years, this mine, beside a lake, has no water in it.
4: The second thing that they all do, after turning on the lights, is to jump on this rickety old wooden elevator to descend 2000 feet. This seems foolish to me especially for some caving "expert".
5: The two-way radios do not look like low frequency cave radios and their reception seems really really good after going through 2000 feet of rock?
6: Can you really get these rocket-propelled anchors that you can shoot into rock that will then hold firm enough to swing from? If so, shouldn't you test them before using them to swing across an abyss?
7: Why does a "caver" need a rocket-propelled emergency beacon?
8: The main character carried a very small back-pack. It seemed barely big enough for the rocket-propelled anchor with about 15 feet of rope, rocket-propelled emergency beacon and explosives that he took. I am not an expert but I would have taken more caving equipment like torches, ropes, helmets, slings, harness.
9: Why do the "laser rifles" need to be cocked (but not reloaded) every now and then? Where does the rock go when it is disintegrated?
10: I didn't know that emeralds actually generated their own light. But they looked pretty.
11: I saw baby monster beetles coming out of a dead mans mouth. If the young are only 2 inches long, then why are the eggs nearly a foot long?
12: Why kill the old man if that meant that they would only be able to make one trip down the mine to get emeralds? Why not leave him alive and sneak down as many times as they wanted and get as many emeralds as they wanted? Why are the bad guys so dumb?
13: Why kill Colm Meanie before he has helped carry emeralds to the surface?
14: Who keeps a loaded shotgun hanging on their living room wall?
In all sincerity, I really like finding a movie with this many gaffs.
