Sadly, I think the shw will get canned. Low ratings. I hope not though.
I will say though, they've never recaptured the Season 1 awesomeness. Season 2 was absolutely horrible and it's been a rocky road since.
I thought the climax was...anti-climactic.
I thought that Sylar was going to battle with Samuel to the death, sacrificing himself and truly being redeemed. Instead we get the copout redemption without seeing it and Peter vs Samuel in a non-epic battle that amounted to camera shaking for the effects.
