Well I had to rush out to see it since Sean Penn won the Oscar. I still say Micky Rourke got hosed.
Sean Penn did a very serviceable job doing an impression of Harvey Milk, but it was not the best performance of the year. People will be comparing other performances to Mickey Rourke's for a long time. Harvey Milk as a movie creation may be a nice touchstone as far as biopic performances.
All that aside it still was a good performance in a good movie. It was a bit square especially compared to 'Paranoid Park.' I think it was unabashedly a message movie, but it was told in a very sensitive way.
I think the most interesting thing about the movie is how "period" it looks with the dated clothing and music but the news reports of the anti gay argument hasn't changed.
