What is the main conflict in Lear by Edward Bond?

Edward Bond's Lear was first produced at the Royal Court Theatre in London in 1971. Bond's 1965 play Saved had already established his position as an important new playwright, and some believe early reviewers of Lear did not fully understand the play but were reluctant to condemn It, largely because of Bond's reputation. Many did find fault with the play, however, and much attention was focused on Lear's tremendous violence. Some were critical of that violence, while others defended its extremity as essential to the playwright's purpose. As with Bond's other plays, the violence in Lear remains a subject of critical debate to this day.
