Dreadful- I couldn't care if any of the characters, except for Pemberton's, lived died or spontanously combusted. The poor stagecraft in the pre-GCSE level fight/struggle scenes to the montone delivery of the lines, the brother with learning difficulties indicated by a hammy childish voice that came on and off like a light switch- the best part of the show was the atmospheric lighting and set design. Save your money & see Patriots- just down the road, now that's an electrifying performance.
Oh and I'm pretty sure that wasn't Paul Kaye playing Ariel
