If Boardwalk Empire had been created 12 years ago, before The Sopranos and Deadwood, it'd probably be hailed as a revolutionary piece of television. While that's not the case, we can see appreciate and relish Boardwalk Empire for what it is--an immersive, historical mob show brimming with exceptional acting, writing, direction, and potential that stretches far beyond the boardwalk.
The $18 million (not a typo) HBO plunked down for the pilot is certainly seen (though the enormous cost does seem excessive), as we're shown location after location, both indoors and outdoors, realistic costumes, and a medley of factors that make it look authentic. And the plot draws from historical figures, like Al Capone, not yet a big shot, and a large cast, each with their own priorities, to fill the pilot with plenty of delicious material, setting up the rest of the series.
Score: 9.6/10
