Even though it took over half the movie to get to the intensity, once it got there the intensity was awesome. The tension brewing with the mechanical parts of the rig was crazy and you couldn't look away from the screen once the disaster starts playing out. The character development was done so well that I didn't even realize that I was connected to them so much until they were in danger. This was a very well done movie across the board.
I would definitely recommend people checking this movie out. It's a great telling of heroism in the face of disaster/tragedy.
