It's all well and good, and the simultaneous sense of an event and an unfinished story to be completed by the audience is impressively engineered. Beyond the occasional image, however, Macbeth is too feebly incorporated to create any sense of a relationship between play and audience. What is intended as an interactive experience instead feels oddly passive, since the level on which one is able to engage is consistently elusive. Punchdrunk have created an intriguing dramatic atmosphere of unease. It would be nice to have something more solid to hang it on.
