Tim Burton's "Big Eyes," a portrait of real-life artists Margaret and Walter Keane, who specialized in creepy but cute paintings of saucer-eyed children and kittens, marks the first time Burton has returned to the real world since "Ed Wood" (1994). Yet while "Big Eyes" is as much an ode to kitsch as "Ed Wood" was, it's also just as much a vampire comedy as his last flick, "Dark Shadows." However, the vampire in this film — Margaret's fame-claiming husband Walter — sucks talent and soul, not blood, and he's a lot less amusing as the film goes on.
