Hamlet Essay: "rotten in Denmark" & how imagery is used to deepen the understanding

[Jake Sousa]

I need some helpful insight on my essay topic. It is: As the play opens, the audience sees Marcellus say "something is rotten in the state of Denmark." How is Marcellus correct and how does the imagery of the play help to deepen the audience's understanding of the play.
A through explanation on where to start, what im 'truly' looking to write about and any passages/ proof from the play would be highly appreciated.
