Thoughts on Hamlet (in progress)

Right now reflecting back on what I have read and the discussions that have been held in class Hamlet knows how to keep his cool. Other sites say Hamlet is crazy and his emotions are out of control but, Shakespeare gives examples throughout the story that Hamlet isn't "crazy" but he is actually emotionally stable and has a set plan and his "out of control" emotions are never shown to anyone. I find it typical Shakespeare and I should have seen it coming that practically everyone in the stories dies. Hamlet is a tragedy. So let's see who is going to die or kill themselves next in this play shall we?
