If I’m not sobbing in a pile of tears by the end of your “Dumbo,” then you’ve done something wrong. Tim Burton’s live-action remake of the Disney animated classic feels like a stretched-thin pastiche of better Tim Burton movies. Reminders of his superior work are everywhere, from the Danny Elfman score to the central character — a bullied, big-eared elephant — who’s a misfit outsider. Dumbo’s awfully adorable, though.
