Not really sure what to rate this...I don't like the play, but the performance is outstanding (just the other way around from Arkangel's 'Twelfth Night'). Nearly every actor performs exceptionally, especially Saskia Reeves as Beatrice and Steve Hodson as the villainous Don John. Bryan Pringle is also very funny as Dogberry, and the musical backing is beautiful, too.
For some this is Shakespeare's greatest comedy, but I think it's strangely soulless compared to 'As You Like It' or 'Twelfth Night'. As to the way Hero is treated, well, I hate to agree with the various feminist commentators, but it isn't a pretty spectacle.
Benedick and Beatrice are the real focus of the play, however, and here are acted brilliantly. 'Much Ado About Nothing' is an absurd play in many ways, but Shakespeare even at his worst has a crazed poetic power which transcends all manner of mediocre plot devices.
