Samuel Johnson wrote the preface to Shakespeare in which he analyzed Shakespeare's style and greatness. Johnson acknowledged Shakespeare had faults alongside his excellences. Three main faults Johnson discussed were: 1) inclusion of evil characters, 2) disregard for time and place settings, 3) loose plots. Johnson was the first to objectively analyze Shakespeare's works, acknowledging both strengths and weaknesses. He agreed with the unity of action but objected to strict adherence to the unities of time and place, especially for history plays. Overall, Johnson provided a classic critical analysis of Shakespeare's works that was original for its time.
