Hamlet Act 1

What the heck is going on? I dont understand how hamlet can even actually function.  He sees his father's ghost and he tells him to avenge his death. Going to funerals bother me. I feel like Hamlet is courageous for even attempting to come to to this ghost and receive the message. Also I think he is alot smarter than his family thinks. Once they realize it, if they realize it, hamlet will not get away with anything. Also he needs to figure out a way t prove his fathers murder. Due to the fact that Hamlet is sort of a disturbed genius (in out smarting people, trickery,etc) he will figure out a way to get to the bottom of this problem. The men who were keeping watch are all noble just because they cared so much to tell Hamlet about the horrid things that  they saw or believed they saw. They are true friends. Well I am sort of anxious to see what is going to happen is the future of this play.
