This is an interesting statement. Perhaps, we "identify" with Hamlet. I am not sure there is much in way of admiration. Hamlet is a character whose "function is smothered by surmise," one who wantonly abuses Ophelia, and an individual who is trapped by the multiplicity of emotions and desires. Hamlet is a uniquely modern hero. Whereas the Classical heroes were ones who waged battle against external forces of evil and possessed a relatively simple dynamic in that enemies and opposition were externally defined, Hamlet's demons are within, his enemies are subjective. In this light, the modern reader identifies with Hamlet because his struggles are our own. His constant battle to simply "be happy" is a modern one, demonstrating that one of the most simple of tenets is one of the most difficult. It is in this light that Hamlet is a symbol of identification, and not so much as admiration.
