This was an excellent movie, filled with great performances, especially Daniel Day-Lewis. This is an old-fashioned epic, in every sense of that word, with a grandness of scale, and underlying themes of obsession and morality. The protagonist, Day-Lewis's Daniel Plainview, is a man of supreme and ruthless ambition, who will manipulate and scheme in order to obtain the precious crude, yet has a blind spot when it comes to those who are close to him. Of course, as in any epic, this ambition comes at a price. If you're looking for a film with lots of action, you may be bored, but if you're willing to be patient with it and let it unfold, you will be rewarded with a rich experience.
