I thought the movie was over the top. It had a point that was important but it didn't need to get so graphic. I didn't like that when the man from the big company found about what really happened he just ignored it and left knowing the truth but never told anyone.
I have to say, Fast Food Nation has to be the best independent film I have ever seen. This film has important moral themes and I can't recommend it enough. Be wary of the R, though. There is extremely graphic animal mutilation in the end at a slaughterhouse, about 25 f-words (with some guy who appears twice using 3 f-words a sentence) a few s-words, people getting high on "crank", some mild sexual slang, and two sex scenes (they were more disturbing than explicit). Also in a hotel room you can hear the sounds of a porn movie (but you don't see anything). Any mature 12 to 14 year old can see this movie. Otherwise it's 15+.
