I've enjoyed a few things he's done but he's hardly ever stretched himself has he? Remenber the dire Henry VIII or Sweeny Tood? Lucky to have had the success he has had imo.
The Cockney Henry VIII is a sure-fire classic for future "Top 20 TV" programmes. In the same way that Adolfo Celi gets crucified for "The Borgias" on every one of those sort of shows... Move over, Adolfo - it's time for Ray's Henry VIII.
