I just hope Sylar stays dead. Please never bring him back... EVER.
I loled at seeing Obama.
No way, Sylar is one of the few interesting characters on the show. He's the reason I kept watching this past season.
Here's the list of characters who need to die on Heroes (my opinion):
Claire
Monica (or at least don't ever bring her back)
Maya (or is she already dead?)
Angela Petrelli
Nathan Petrelli
Micah Sanders (or at least never ever bring him back)
Niki/whoever the fuck Ali Larter plays (holy crap I am so sick of her DIE DIE DIE)
