The Adjustment Bureau

I recently saw the movie The Adjustment Bureau and thought I should write on it. The movie is about whether we have the choice of free will or if our fate is mapped out. It also brings up what god is and whether he/she actually exists. During the entire movie, Matt Damon is trying to change his fate to be with the woman he loves. People, or "angels", constantly try to prevent Matt from doing anything that could potentially ruin the plan (or his fate). I won't tell you if he ends up with the woman or not, but it brought up the idea if we have free will or just the illusion of free will. Do we think we make all of our decisions but it is actually controlled acts of fate?
