I enjoyed it. An interesting film, based on a novel whose story is set in the 90's, yet Edward Norton rewrote it to give it that post war 50's feel, the jazz age, Harlem and guys wearing pork pie hats.
It's owes much to the Film Noir genre without being too dark, think neo film noir crossed with Road to Perdition and a touch of Mike Hammer tossed in.
The original book uses modern day gangsters as the main protagonists but Norton wrote the screenplay around the corruption of the corporate world instead, the Tammany Hall era, with, dare I say it, a nod to the current crop of mega billionaire corporate bosses, think Trump, Rockefellers, Rothchild, Gates, Clinton, Bush and the Royal Family, the 'illuminated ones', who actually are above the law. In fact Baldwin gives Norton a lecture about power being omnipotent, much like the quote Trump was caught saying at a party once!
