DUDE, seriously. He's not good looking, he lacks charisma that some marginally okay looking guys have that makes them sexy (for instance, David Thewlis above is not conventionally handsome but he's an awesome actor and he has that something about him that draws you in), and I'll go a step further and say he's not that talented either. Sylar lost A LOT of scare-appeal when he took over the role. He's too fucking cartoonish to be a good villian.
