I confess I knew nothing at all about this play before last week. It's a somewhat weird meditation on the political process. There is a sort-of viewpoint character, "The Bastard" who is the illegitimate son of John's brother Richard Cœur de Lion; yet at the same time he consistently argues for a more vigorous and vicious engagement by the English against the French and/or the Pope, including at times when this is obviously a bad idea. So although he is definitely the author's creation, it is not at all clear that he is the author's mouthpiece.
King John himself is also an ambiguous figure. His bold words against the Pope in Act 3, which sound terribly impressive in post-Henry VIII England, melt into historical footnotes in Act V. The cosmic karma that descends on him for killing Arthur is unfair because a) his orders weren't actually carried out, b) he changed his mind and c) Arthur dies by accident. John (and by the end of the play Henry III) may be legitimate, but that doesn't make you right. It's not at all obvious that John's agonising death is deserved.
I'm surprised that this play isn't better known. Apart from the title role, the Bastard, Constance, Arthur, Hubert and Salisbury all seem to me to be rather interesting characters who could be brought to life under the right circumstances. Arkangel have a decent cast, none particularly outstanding, but it is good material and they deliver a quality product.
