"spectacle" is a good way to describe Artaud's vision of true theatre. His Theatre of Cruelty is one that is both horrible and fascinating at the same time, something like a train wreck- you want to look away, but you can't help but watch. Everything is grandiose, everything is big and loud, everything is important, and everything grabs your attention, shakes you, and doesn't let go until the show's over.
