text: A group of cavers with a sad history take an author on a 'hairy' adventure through an uncharted cave in Kazakhstan. In these times of remakes and sequels and film companies trying to cash in on any winning combination of cinematic components, The Cavern has only one relatively different twist on the previous eight cave movies over the last few years, and that twist seems to be taken from an X-File. I like to give every film the benefit of the doubt, but there were just too many little annoyances for me here. The camera work can give you a headache as they seem to constantly confuse which way is up. Not being a caver, it doesn't really matter to me whether the filming was realistic. There is entirely too much unnecessary PANNICK from supposedly experienced cavers, by the last half you're saying out loud one of two things  oh just shut up and concentrate on saving yourselves, or I hope you all die by the end. It must have been very tiring for these decent actors to make this film. A moderate amount of gore and nothing special in the dialog or characters. While you're pretty confident you know what's going on by the end, the last five minutes explain all the details. But I would have had a better opinion of the movie if they would have left the last minute on the cutting room floor. It just wasn't necessary. I suggest you hit eject immediately after your suspicions are confirmed and save yourself the setup for the sequel. I've long thought that the film industry should share a modified restaurant industry's checkout scheme. You pay for the materials to make the film before you go in, but any profits for the film come from the tips you give when you leave the cinema. I can't blame what I don't like about this film on its low budget.
