Query: A fantastic thriller for adults

The slow-boil thriller is a genre that I immediately respond to and Roman Polanski is certainly the master. With "The Ghost Writer" he crafts, what I believe, to be his best film next to "Chinatown". With crackling suspense, spot on acting, and a plot that is always compelling, relevant, and well told, you get one of 2010's finest films. The picture is so well made (expert cinematography, a memorable score, snappy editing) that it's almost unbelievable. Roman Polanski is back and in top form.
