I went into this screening with low expectations, because I had been told it was not a particularly good film. And, yes, some parts are just a bit hoaky, some characters are stereotypes, and there are some inconsequential goofs (dry clothing in the truck cab, after full immersion in the lake).

BUT, all that aside, the movie kept us on the edge of our seats for much of the time. It was an enjoyable evening / after-dinner movie! And, it is frankly much better than quite a few rather lame films that have come out, with thunderous publicity, in the last 18 months.

The plot involves a rescue mission, directed at saving workers in a collaposed mine. There are quite a few surprises (not outlined here, lest the comments become spoilers), so the plot is not particularly predictable. The all-too-common 'hyper-angst' that is frquently used in such movies is kept reasonably in check, so the action, and plot twists are at the forefront. Yes, there are several 'personal' storylines going on that form a backbone of the plot. But, they actually contribute to the suspense, rather than detract from it.
