It's a silly, stupid movie. People make silly, stupid movies, whether they be Turkish, American, British, German, what have you.
Especially when politics start getting involved.
The thing to remember is, these are works of fiction. It isn't right, it isn't wrong. It is nothing more than someone expressing their views in a handy format. This film is no more true than a boxer taking on the evil, Soviet Empire with the help of the Mujahideen, or any of the countless movies depicting Arabs as violent, terrorist bastards.
Don't let it bother you. Anywhere there is a camera, you can find as much good as there is bad. Letting some film that happens to portray Americans as something other than "fantastic people who always do good" go to your head is just, well, stupid.
