An amazing film - for the first hour
The first hour was remarkable - it had the likable family, good acting, a plausible scenario - everything - it had me sitting at the edge of the seat the whole time. The last 30 minutes took a big hit - the acting went downhill and the story became less and less plausible.
At the end of the day, this movie reminds me of 'No Escape' with Pierce Brosnan - as a film with a 'vacation gone horribly wrong' type of scenario. The last 30 minutes really did cause the movie to lose some very big points, but even then, I still saw it till the end, wanting to know what happens to his wife and son.
All in all... I'm still going to recommend seeing this film. Even with a big hit in the final act, there is still a lesson to be learned here - and the first two thirds of the film will grip you like few other films do.
