You are mixing up realism with what makes a good movie. A good movie should have story and plot. If you want to have a realistic movie about war then I guess the first 30 minutes would be about getting from the USA in a transport plane, then getting delayed in Germany, then being re-routed via Saudi than going straight to Iraq and then settling in and making your mess a bit more homely and then .... you end up with the worlds most boring war movie.
For a good war movie we want STORY not realism as per the above. Given that the modern day soldier has no more credence than Paris Hilton and should be cut out of the equation altogether.
Black Hawk down is still rubbish and it is still not a war movie. They even pinched the bit where the 2 guys were fighting off the millions of Somali's from the helicopter from the film Zulu.
"Somalies, thousands of them ! "
Oh dear....
