Overall it was a good movie, but I felt it was very drawn out. Certain parts of the movie did not seem plausible.

It was suspenseful throughout. With so many movies in this genre currently available, it still managed to remain exciting and kept us engaged from beginning to end!

Good entertaining film. Sad but felt real. Pray this NEVER really happens!!! NEVER!!!!!

Good story line, with okay foreshadowing. Camera crew did a job framing shots and nice camera movements to draw the viewer into the action. Special effects were believable and not to over the top. Gerard Butler did a great job in the hero. Over a very good film. Would watch again.
