Based on harrowing true events will the team be able to put their egos and drama aside long enough to find a way out or will the merciless force of nature consume them?
The lack of the 3D gimmick aside SANCTUM is a passable action/survival flick, filled with the requisite cliches and stock characters such as the father and son duo that have a strained relationship, depicted by Richard Roxburgh and Rhys Wakefield, among several others. And while the dialog was obviously put on the back-burner some of the tensest moments come from the characters pulling together and trying to work to the admirable goal of not drowning with varied degrees of success and that primal motivation is successfully relayed by actors in a pretty raw way, if a little heavy-handed.
That sense of doom is layed on pretty thick for most of SANCTUM, it has a similar urgency of other survival flicks like THE POSEIDON ADVENTURE and if the characters stop moving for too long something bad is bound to happen. So they stay pretty mobile scouring the cave system looking for salvation with all kinds of challenges along the way that either pull them apart or make them stronger. But Mother Nature is definitely in a take no prisoners mode and there was actually a pretty surprising and particular gory sequence that you won't immediately forget.
We've essentially seen this movie before, it's the quintessential man vs. man vs. nature survival flick, but it's setting is eerie, unique and it is interesting to see the plot unfold and fairly entertaining trying to predict who might make it out alive and who's cave-diving ticket is about to be punched in the same way watching an old slasher movie is.
SANCTUM, while it's lacking its huge 3D selling point here on DVD, is a pretty harmless survival flick that will have you guessing at who is next on Mother Nature's sh*t list and might just give you a new found respect for real cave-divers ... or maybe just make you shake your head wondering why in the hell people actually go out and do it.
Then you'll take another bite of popcorn and come across CLIFFHANGER on TV.
