Compare this to "The Cave" to really appreciate it

Rating: 7/10 (8 March 2006)

Great movie with probably one tenth the budget of American film "The Cave", but far more effective.
The movie is simple, a group of friends, including a woman who has lost her family in a car accident, go spelunking and find a culture of cave-dwelling carnivores. Its the execution that makes this exceptional.
The cast is entirely women, yet there is no leering nude/makeout scene. This movie does not insult the viewer. Instead of large, well-lighted sets, and uninteresting character buildup, the movie is lean, and even though the first creature isn't spotted until roughly forty five minute mark, the beginning never drags. Its claustrophobic, well shot and framed, convincingly acted, and I refuse to spoil a really cool horror movie ending. So of course, it hasn't been released here yet, and we may never see, and I suspect if it is released, the studio support will be flaccid.
