"Vol. 2 makes a compelling case for a more serious interpretation of Tarantino’s talent, and the film justifies the otherwise vapid (and very cool) Vol. 1, which should never have existed as a separate film. The commercial logistics of a four-hour movie aside, Kill Bill would have worked best as a single entity, the second half imbuing the first with a certain weight. Indeed, Tarantino’s lip fetish is itself enough to empower Vol. 2 with far more powerful scenes than Vol. 1: when a tied-up Beatrix must wrap her lips around a flashlight, the degrading image is worth more than any moment in the first volume. Here Tarantino employs the same technique as in Reservoir Dogs, where he subtly focused on his characters’ ears before slicing one off in the end. It’s a cruel trick, but a crafty one—and proof that Tarantino plays more than lip service to the art of film."
