Finally watched the movie after the second sitting. It is dark, brooding with subtle (maybe only for me) undertones which I am grappling to understand. Probably need some better background of American history and the way this country was made, to appreciate the movie more fully.
What stuck me was the resonance that the theme of the movie set in early 1900s has with the situation in America today? Religion's dependence on big money and the big money's discomfort with it. Atleast that seems to be what is happening even now. But I guess the situation is similar in other countries too.
Addendum: To make up for my dreadful attempt at review up there, I will link to Steve Sailer's long, informative and interesting review. And in case you do not have time, or you have read Sailer's review, then read this short and cute review at the ambler.
