What is the author's style in Ghosts by Henrik Ibsen?

Ghosts comes from a period in Ibsen's career that is considered his realist period, during which he wrote about social issues that disturbed him and his audience, with the hope that examining such unpleasant truths would lead to social change. In this play, he is unmasking the hypocrisy that is usually behind memorials to great civic leaders, looking at the damage that a man with a great reputation might leave in his wake, the "ghosts" that linger.
