What is the author's style in The Elephant Man by Bernard Pomerance?

The Elephant Man is classified as a melodrama, which are plays in which the plot offers a conflict between two characters who personify extremes of good and evil. These works usually end happily and emphasize sensationalism. Other literary forms that employ many of the same techniques are called melodramatic. The Elephant Man offers both good and evil in the personifications of Merrick and Ross.
