In 'Princes in the Tower' Channel 4 have shown the BBC just what historical drama is all about. A meticulously researched piece of work with beautifully rounded characters that follow the historical events and evidence ie not the Tudor spin, in a roller-coaster ride of absolute excellence. All of history's archetypes and stereotypes have been laid to rest, particularly Richard III, and the real murderer of the Princes finally exposed. Mark Umbers plays a mesmerising Perkin Warbeck and his famous line to describe his father's (Edward IV's) character which I won't repeat here (I want you to enjoy it for yourselves when it comes) is one of the best lines I've heard on TV. A masterpiece! Give us more Channel 4!
