Dean Winchester- I used to Amore his character in season 1, back before the fanbase turned him into some sort of 'gift from the God's' above. Is he sweet, funny and hot? Hell yes. Does he deserve to be worshipped as the center of the freaking earth? hell no.
Greg House- Again a character that started off brilliantly, but has since then become absolutely ridiculous. Seriously, would te want that guy treating te as a patient, like a lab rat, for his own amusement?
