Oh goodness. Why didn't somebody stop them!
The story in its essence was very good, however the delivery is idiotic. Over directed in the most silly, childish ways; melodrama past any point of sanity, and poorly written so that it loses all sense of reality. In fact, this should have been fantastic because the essence of the survival story is extraordinary, but because the writing is so lacking, and the direction is horrifically childish, over the top and silly, they lost all the power it should have had. They should have studied Ron Howard's Backdraft to understand the power of a "fire" movie and what it could have been, not whatever they looked at as their example.
This was embarrassingly bad, and for no good reason other than too much ego to go hire a real, decent Director, and Writer. Even an excellent Director could have worked with this idiotic script and made it work. It would have been an entirely different film. Sad they didn't do that.
