Alright I watched the whole thing but not from love for the movie or a curiosity to know the climax (which is very predictable) but just because I liked the music score and I found the acting decent. Also because I had some time to kill.
The storyline is of two Christian missionaries being kidnapped for ransom and the ordeal they have to go through. Sounds like a Good tale right? NO, the problems come from them repeatedly giving their thoughts on Christianity and Jesus almost every time they talk (other than the bit where they talk about the NBA). Towards the end, the preaching started to grate on my nerves and also the other scenes where their families were being shown.
In short, if you are Christian and believe that the Christ is your savior and died for your sins, then go ahead and watch it. Others, just stay away. The 4 in my rating is for the music score and I quite liked the Russians.
