James Cameron's name is all over this cave diving adventure but he is only on board as executive producer.
A group of explorers are trapped in a cave system when a Cyclone strikes and must find their way through the underground, and sometimes underwater, maze to survive.
The best thing that this has going for it is the amazing scenery and some vertigo inducing moments, all in nifty 3D.
There is a Father / Son bonding sub-plot but it's all just a bit average and none of the characters really come to life.
This is inspired by a true story which I suspect would make a better documentary than it does adventure movie.
