Saw both United 93 and "Thank You for Smoking" recently they were both excellent, for different reasons. United 93, no matter what your thoughts are on 9/11 and Bush and everything is a must see. It is simply presented as a documentary retelling of the events of that days from the perspective of the passengers, FAA, and families. No hype, no blame, no overly mushy crap.
Thank You for Smoking is a movie about a tobacco lobbyist and raises the issues of "flexible morality" and what happens when your kid might start following in our footsteps. Funny, sarcastic, and well written. -- Brian
