Sanctum is a cave adventure movie directed by Alister Grierson, and starring Richard Roxburgh Ioan Grufford and Rhys Wakefield, and produced by James Cameron. The two most outstanding things are the visuals and the characters.
Sanctum is a action-thriller where a team of cave divers go on an expedition to the largest and least accessible cave system on Earth. When a tropical storm forces them deep into the caverns, they must fight raging water, and deadly terrain as they search for an escape route out of the cave and to the sea. Master diver Frank McGuire has explored the South Pacific's Esa-ala Caves for months. But when his exit is shut by a large boulder following a flash flood, Frank's team-including 17-year-old son Josh and financier Carl Hurley are forced to radically alter plans. With severely dwindling supplies, the crew must navigate an underwater labyrinth to make it out.
Let’s start with what’s good with this movie. In classic James Cameron style this movie is beautiful, almost everything about it is amazing to look at, the underwater effects, the lighting, the actors themselves, the scenery towards the beginning, and the 3d adds a whole new affect to the claustrophobia the film produces.
Now we can move on to the bad parts, Number one: the writing is simply painful, especially towards the beginning, not only being totally unbelievable but it just sounds stupid and produces a lot of face palm moments. Number two: its simply too predictable, all the “twists” are always obvious and every plot point is too easily predicted, which makes the film boring, all scenes where they are not close to death are boring, especially the long talky scenes towards the beginning, although it looks good its simply too boring and predictable. Number 3: the characters are completely one dimensional, with no depth, and no believability, which is partly due to the bad writing and partly due to the average acting.
Overall I would compare this movie to a stupid pretty girl who is nice to look at but is so boring, predictable and stupid it makes nobody want to have any thing to do with her. Altogether I would give this movie a 2 James Cameron’s out of 5, and I would recommend this movie to anybody who loves sitting back and zoning out to some great scenery shots and water effects.
