That is tough. The whole reason I even watched the pilot was because of Dominic Monaghan but I was hooked after seeing it. Hurley is the best comedic relief ever. Sawyer is that character that you want to hate but sometimes just love. And of course Charlie, I cried every episode where Desmond had visions of him dying and screamed in agony (slight exaggeration) when he died. Soooo I have 3. NO!!!!! My other top of the list choice is Daniel Farraday. Love love love love love him!
