Full as it is with ideas from, and allusions to, Todd Haynes’s other films, Wonderstruck still represents the director’s most dispiriting work to date. This story of children finding themselves through their discovery of art and the past is adapted from Brian Selznick’s Y.A. novel of the same time, so it inevitably bares some resemblance to Martin Scorsese’s 2011 film Hugo, which was also a Selznick adaptation. But the better comparison, ludicrous as it sounds, is an entirely different Y.A. adaptation, one released the same year as Scorsese’s: the execrable Extremely Loud & Incredibly Close. Haynes, with a film light on dialogue and entirely too reliant on Carter Burwell’s impressive, ever-expanding and changing but nonetheless incessant score, draws on the hollow sentimentality of his premise rather than the emotional specificity of his characters’ engagement with the art and history that saves them.
