the movie be entertain and but become frustratingly unrealistic in the last half hour . i would not tell you exactly what happen but i be yell why do not they do this or that and or you have get to be kid me for almost the entire last half hour . especially the end where the victim be locate in a place where there be no chance they could have have access to and but they be still spot immediately by their rescuer . i believe you should suspend disbelief to a point when watch a movie and but the movie maker also have a responsibility to keep thing within the realm of possibility . i be a professional firefighter so i understand that in a crisis a lot of people do stupid thing and use bad tactic when face life threatening challenge . but to me it would be more entertaining to see people who be use good judgment and not freak out .
