[How to Write an Introduction]
Your introduction only needs to do a few things.
Here are the steps (remember, these steps actually go in order):
1) Provide a hook to get the reader interested. Make them want to keep reading.
2) Introduce your theme. Why is it important?
3) Talk about the theme and the play. How do we see the theme in the play?
4) State your thesis. One simple sentence that sums up your paper (and usually mentions your theme)
Here you can see all of the steps in an example paragraph:

His descent has been so impressive and widely publicized that one can't help but watch in horror as if witnessing a car crash. [2] Insanity, or madness, is such an interesting thing that people wait with baited breath to find out what will hapen next. [3] This theme of madness is exactly what makes Shakespeare's play Hamlet so fascinating. [4] Shakespeare uses madness, not only to keep the audiences attention, but to reveal much about it's effects on people.
