Among the leads, Radcliffe alternates between playing the wet blanket and the dry wit, and Grint strikes a few sparks as his ambivalent protector.

More than even the most faithful of the earlier episodes, this film feels devoted above all to reproducing the novel onscreen as closely as possible, an impulse that drags it toward ponderousness at times and rather sorely tests the abilities of the young actors to hold the screen entirely on their own, without being propped up by the ever-fabulous array of character actors the series offers.
