WONDERSTRUCK is a Todd Haynes film. It is a masterpiece of design. Surprised? I didn't think so. Yeas, its not only about museums, it's about "the museum." But much more: the subject (and object) of this picture is serendipity and revelation. Something this earnest and open-hearted was liable to be a bit emotionally clumsy. All the more endearing for that, say I. Clumsiness excused or not: packs an ENORMOUS payload.
