Based on the non-fiction expose about the dirty secrets of the fast food industry, this is a fiction adaptation directed by Richard Linklater, and co-written by him and the book's author Eric Schlosser.
What we get here are a series of interconnected stories revolving around the various people involved with a fast food chain, and the role that the restaurant and various aspects connected to it affect all of these people, and vice versa. It seems like a rather odd and challenging way to adapt a work of non-fiction, but somehow it kinda works.
Granted, the film barely scratches the surface, and seems a little too neat, tidy, and convenient in places, but it strikes a nice balance between being a message movie like the similar Super Size Me or Food, Inc. and still being entertaining without too much pretense or over-the-top manipulation to make a point. Yes, there's some disturbing moments and images, but it's not as revolting and off putting as you might be lead to believe.
Instead, it's rather nuanced. and more about the human stories and the role of fast food within culture as opposed to being an extremist piece of muckraking propaganda.
As he is good at doing, Linklater has a wonderful ensemble cast lined up for this which includes Ethan Hawke, Greg Kinnear, Patricia Arquette, Bonbby Cannavale, Wilmer Valderama, and two wonderful,. if not brilliant appearances from Kris Kristofferson and (especially) Bruce Willis. Most of their performances are pretty good too...for the most part. Avril Lavigne sucks it up, but at least she's not in it for too long.
All in all, a pretty decent film. I'm not going to become a vegetarian as a result of watching this, and it didn't tell me a whole lot that I didn't already know, but at least gave some more awareness and the arguments that are made are pretty well balanced are well done, too.
