Sanctum: Not worth the dive!

Expert diver Frank McGuire and his teenage son Josh head an expedition to map a network of underground caverns but when a tropical storm cuts off their exit, they must use all of their wits and strength to find a route to the surface.

What should have been an uplifting drama about the struggle and eventual triumph of a group of regular people to survive some rather unfortunate circumstances turned out to be a dull, dreary and even malicious waste of the audience's time.

It felt like it took Alister Grierson (who directed the film) forever to get the film setup and then moving. That was due to the fact that both the characters and conflicts they were dealing with were monotonous. The audience would be hard pressed to find a character within the cast to root for as they were all aggrevating and/or insipid in some way. Even when there were moments for the audience to gravitate to someone like Josh, Frank or another member of the cast, something awful would happen to someone and they would suffer a fate worse than what would happen to some hapless teen in a slasher film.

Not even the name of James Cameron (who served as Executive Producer) could save Sanctum from being a depressing waste of time.
