I thought it was a very good movie. Ledger makes for the world's coolest villain as The Joker.
I think looking for social and political commentary in this movie is pretty pointless but it entertains like many movies can't.
Long as I remember The rain been coming down. Clouds of Mystery pouring Confusion on the ground. Good men through the ages, Trying to find the sun; And I wonder, Still I wonder, Who'll stop the rain.
