Diagnostic Misconceptions - Ambiguous Ending
English Lit: AQA GCSE Macbeth, topic 2.3.4

The play does end happily in the sense that Malcolm is rightly restored to the throne – ‘Hail, King of Scotland’ exclaims Macduff in Act 5 Scene 9. However, those words reflect the cries of ‘Hail’ from the three Witches in Act 1 Scene 3. This subtle mirroring casts a degree of uncertainty on the longevity of Malcolm's reign. A happy ending, no doubt, but also a menacingly ambiguous one.
