English 12 Hamlet is he resolute or irresolute

Today we discussed whether Hamlet should be interpreted as a 'man of action' (resolute) or a 'man of inaction' (irresolute) -- I subscribe to the idea that he is resolute. We took a few notes on this and watched 10 minutes of another movie that showed Hamlet as a man of inaction.
We took some notes on the background of Shakespeare's life.
We completed an Act 1 quiz.
We also read Act 2 scene 1 and had the following exit slip assignment:

Why is Ophelia so upset at the end of Act 2 scene 1 (i.e. what has happened?).

Please try to be specific.

No homework was given.
