The last 2 paragraphs of the review moved me:
http://rogerebert.suntimes.com/apps/pbcs.dll/article?AID=/20081124/REVIEWS/811240297Milk" tells Harvey Milk's story as one of a transformed life, a victory for individual freedom over state persecution, and a political and social cause. There is a remarkable shot near the end, showing a candlelight march reaching as far as the eyes can see. This is actual footage. It is emotionally devastating. And it comes as the result of one man's decisions in life.
Sean Penn never tries to show Harvey Milk as a hero, and never needs to. He shows him as an ordinary man, kind, funny, flawed, shrewd, idealistic, yearning for a better world. He shows what such an ordinary man can achieve. Milk was the right person in the right place at the right time, and he rose to the occasion. So was Rosa Parks. Sometimes, at a precise moment in history, all it takes is for one person to stand up. Or sit down.
