Tom Jacobs seeks it out:
When done right, scenes of violence slap us out of our general stupor, they make us see things again in strange ways. … Violence tends to focus the attention (It’s the “purest form of expression,” as Herbert Marcuse once said), even as it unveils something of our vanities. Violence (which is different from suffering), when represented in fictional form and crosscut with a sense of humor, is in today’s world, perhaps the only way to make us see. And laughing while we weep, well, that’s a particularly rare experience—and one that ought to make us think about what lies in between.
(The rest of that long scene from Kill Bill here.)
