1. Peter v. Sylar was a total non-event. You know for someone who has TK, flight (more on this later), telepathy, regeneration, time and space manipulation, invisibility, super strength (at the end anyway), possibly intangibility, and God knows what else I'm forgetting, Peter was pretty damn useless throughout this whole series. Which I'm willing to forgive for the sake of the whole "finding himself/controlling his power" thing, but he seemingly got through all of that talking to the old black dude there at the end. But what does he do? Gets chocked by Sylar and is basically a distraction for Hiro to come in and do the stabbing? Sure he gets a few shots in when he gets Jessica's strength I guess, but I really was expecting more. This show has always been about the whole comic book experience, if they would have stayed true to that they could have given us half an episode of Sylar on Peter (OK that sounds wrong).
2. Killing Nathan (we assume). WTF? Peter, you can fly! You need your brother to come in and do it for you? Isn't this a lot more meaningful if Peter figures this out for himself, overcomes his doubts in his powers or whatever and heads up into the clouds on his own? Why bring Nathan into this?

I just don't understand what the writers did to the character of Peter at all. Him gaining all these powers, learning how to control them, and going on this journey where he comes out from his brothers shadow and becomes a hero is one of the major overriding arcs of this show from the start. It was working pretty well too, right up and including his last run back to Nathan, and his conversation with the old black guy. And then at the end it's all stripped away from him by the writers. He does relatively little to stop Sylar and his brother bails his ass out yet again. Why? So you can milk the "Peter doubts himself and needs to learn to control his powers" storyline for another season? If you think you have to do that because otherwise he's too powerful for good storytelling, then kill him off. Or at least have him fly up there on his own and go off to meditate or something afterwards until you can figure out what to do with him.

3. Dammit, kill Sylar already. I know the show is blowing up and you think you have to keep all these major characters around to ensure the shows success, but that's not the case. We're adults, if you give us compelling stories we'll keep coming back for more. But don't let Sylar live just because you think you need to keep him as a villian.

On the plus side there were some good things about this episode:

1. Molly's description of "the other bad guy", who's obviously going to show up as a villian next season. Some kind of super-telepath maybe? Maybe a Shadow King type storyline? I'm interested.
2. Jessica. Most seem to hate this character and she was never one of my favorites, but I found myself actually enjoying her/DL's/Micah's stuff the past few episodes.
3. The Silver Surfer trailer? Jenn asked me when that was coming out and my response was "Not soon enough". Damn that shot of the Surfer eating a missile with his board was hot. It's exciting and a good sign to me the makers of the movie apparently have the wisdom and insight into the material to make the Surfer's powers almost magical in nature.
