I can sum up last night's episodes for me in one word:
I kept looking at the clock to see if it was over yet and it seemed like the show kept getting longer and longer and longer.
I don't care about Sylar anymore. The writers ****** up and made that character too powerful while zapping all of our heroes. And now they just have him as the go-to bad guy. but he's a terrible bad guy. he has no plan to dominate the world, he's not looking to get rich or pick up hot chicks. He just kills people. That doesn't make a good villain to hang your series on. that's the kind of villain you spend, at most, 1 season tracking down then you kill him and move on to something new.
This season only picks up six weeks after last season. Claire getting a GED and then into college in 6 weeks is pretty unbelievable. Her mother already hooking up with a new guy that she wasn't already involved with? It's just weak storytelling.
The carnival angle is new and could possibly be fresh. Other than that? They need to mix things up. New characters, get rid of some dead wood, and that includes Sylar at this point. My favorite character from the first season was Hiro. Period. But they screwed him up so much over the last season and a half that I can't stand to watch his segments now, get rid of him. Niki/Tracy/whoever, she needs to go. I'm glad Danko is gone, that's a start, now they need to finish cleaning things out.
