For a war movie Rescue Dawn has almost no conflicts

I've just finished watching Rescue Dawn a few days ago. A few of my colleagues also watched it. Some liked it, others not too much.

For a war movie based in Vietnam, somehow I just can't feel the conflict and the OMG-what-are-they-going-to-do moments. While Christian Bale was tortured continuously, at no time did I think he was going to die. When he decides to escape, one of his prisoner friends threatens to tell on him. That's the only conflict in the movie. There was no tension anywhere else.

This is a very strange movie, especially when it's rated at 90% on rottentomatoes.
