"Hugo"’s eponymous protagonist (Asa Butterfield) peers wide-eyed through the glass face of a 1930s Parisian train station’s main clock. The bustling station scene he observes from this vantage point is busy enough, filled with all the requisite archetypes — the stern but bumbling station inspector (Sascha Baron Cohen), the cheery florist (Emily Mortimer), the cosmopolitan travelers and city ruffians — and yet despite it all, the whole sequence still felt tiring to me.
