All writing is open to interpretation, and Shakespeare lends itself to this more than many others. The work here is largely focused around my interpretation of Shakespeare's play, which is that Macbeth's actions were the result of a magic spell.

Though there is plenty of evidence for this in the play, and there are commentators who see it this way, a more common interpretation is that Macbeth seized the throne because he was ambitious for power.

Neither interpretation is "correct" but understanding a range of opinions is essential if you want to get a top mark in your GCSEs.

Remember: any argument, that's backed up by the text, is fine. What's here is just an opinion...
