Dr. Romano, ER
Romano made it so easy to hate him. Pompous, rude and always armed with a stinging — and sometimes racist — putdown, he made the lives of nearly everyone at County General miserable, so much so that almost none of them attended his funeral (after he was crushed by a helicopter, of course). But as it turned out, underneath all that bravado was a man with some heart: He pined after his dear Lizzie, broke down after Lucy's death and secretly communicated with Reese via sign language. So, we loved to hate him and hated to love him too.
