Having an allergy to films that are 3 hours long, I fully expected to come out in a rash of boredom and sore-backside syndrome. Fantasy fluff isn't really my thing, especially when it involves 9-foot smurfs, 3D CGI ('the future of cinema!!!'), and a plot that has as many twists and turns as a metal ruler. But I thought this was rather good. It certainly went by quicker than 3 hours and there were no complaints from the rear.
