Well, aside from being misled about this episode from the previews about this episode, I'd have to say that overall I'm disappointed with this episode.
Oh wait.
Firstly, and I can't make this clear enough, I hate Sylar. He is a bastardization of what he was set up to be in the first season. So naturally I have any bias against Sylar-centric episodes like this one. That being said, the parts of this episode that didn't involve Sylar contributed to the overall "filler" feeling of this episode. Nothing of any relevance was really shown in this episode (except for more Sylar exposition who's had 39872 times more delving into his backstory than anyone else on this show; Is it absolutely necessary for this character at this point?), and when we finally got to the end we wind up with just as much information we had when we started. Sylar likes to kill. We needed a whole episode of him going Norman Bates just to know that?!?!
Aside from that, the side stories were almost as relevant. We know that Hiro is still a snob towards Ando. All Ando ever wanted was to even be in Hiro's league and now that he's the Crimson Arc, Hiro once again feels the need to be a jerk. I mean, for a guy who apparently became all emo in 5YG because Ando had been killed, he sure knows how to snub his nose at him. Getting just a bit tired of that dynamic.
Matt and his wife. Or ex-wife. Or something. Yeah, I understand that Matt and Janice have a history. They have a child together now. And now all of a sudden he wants to be back with her. Wait, didn't she break up with him, or he left her or... bah, nevermind. It's not like Matt has been sliding between women anyways. Especially ones he felt he was destined to be with because he went on a spirit walk or some nonsense. </dripping sarcasm>
The worst part was how Sylar took a knife to the back of the head, and just got right back up, as if getting 4 inch steel embedded through your brain will just leave you functioning no problems. Not even Claire can just bounce back from that. It's just another step to Sylar never getting his comuppance. Even Micah's indication that Sylar could be the hero everyone needs makes me sick. Wasn't that supposed to be Peter? Or Nathan? Or, well, anyone besides Sylar?
It's disappointing that every season builds to nothing more than, "Okay, we gotta kill Sylar," and "Well, looks like Nathan's going to be killed." You would think that maybe that part of the forumla is what's keeping this series stale.
Sigh. I miss Adam...
