Others have written about this amazing film - and of course a film based on an Upton Sinclair story starring Daniel Day-Lewis has to be extraordinary, but to my mind Paul Dano was the revelation here (pun intended). It's no mean feat to meet and even surpass a Day-Lewis performance, but Dano does it.
Menacing from the opening sequence, it's a twisting, turning tale of greed, narcissism, hatred, and inhumanity - with the occasional glimpse of light and kindness.
Watch it.
