Well, first time I saw it I found it very entertaining. On the 2nd viewing though, and I find it helps to see a movie twice if I can bear it at all. I have a thing about gullibility. Trying to imagine a military leader who would EVER allow a civilain dictate how an operation would be run even on an innocuous level is very implausible.
What is impossible to believe though is the fact that a supposedly experienced military leader would I) bring a large potential 5th Column on an op that requires the utmost syncronisation and stealth. II) He would commit suicide for a group of people that existed outside the parameters of his objective.
I am interested though as to why I found it so particularly entertaining on the first viewing.
