If you've ever wondered about a "day in the life" of a lobbyist and what they do for a living - great movie. I'm in government affairs, and this pretty much has been my career trajectory, down to the starting my own consulting firm. My friends ask me if this is tongue-in-cheek, and my response is its more close to reality than absurdity. One of the characters in the movie was fashioned after a woman I replaced - so hits very close to home.
I've compared notes with my colleagues in the business, and we've all seen it and laugh.
Is it right for you? Depends on your sense of humor and what you like in movies. If you like watching the Colbert Report and the Daily Show with Jon Stewart, there is a high probability that you will enjoy this movie.
