Shutter Island, Martin Scorsese's operatically paranoid adaptation of Dennis Lehane's 2003 suspense thriller, is easily the best movie of 2010 thus far, so it seems a bit churlish to wish that was higher praise. Don't get me wrong: Even running a wildly overlong 138 minutes, the film is mostly terrific, and one of the very rare works of its kind in which your interest actually increases during the final reels. Yet given Scorsese's glorious technical acumen and the efforts of a ridiculously gifted cast, I still left the cineplex feeling that it just missed greatness, and not even greatness along the lines of GoodFellas or The Departed - more like the genre excellence of Scorsese's 1991 remake of Cape Fear. Shutter Island is a strong, worthy offering, yet as far as this year's releases go, it's only a few degrees more satisfying than Youth in Revolt or Daybreakers. But hey, it's early - I'll happily take it.
