See it if you want your Shakespeare to be action-oriented and visceral. Nicholas Martin-Smith is excellent as Titus Andronicus.
Don't see it if you don't like Shakespeare plays. You are annoyed by al fresco hard seats with helicopters and other noises competing with the actors.
See it if You enjoy Shakespeare as a visceral experience and not just a cerebral one.
Don't see it if You're put off by blood, gore, cannibalism, rape, and dismemberment.
