Examine Hamlet’s first line of the play. How does he feel about his stepfather?

Claudius publicly inquires as to how Hamlet is feeling. Our melancholy protagonist states that he is "A little more than kin, and less than kind". Hamlet says that although Claudius is now more than family, his mother just married Claudius) he (Hamlet) is nothing like Claudius. Hamlet is clearly not impressed with his uncle.
