They must have, because the one I saw was one of the worst cop outs I've ever seen. For a show that was normally so unpredictable, you can't really afford to have a climax that's so... anticlimactic and predictable. I know the writers know how to write a satisfying climax, just from the earlier episodes in the season. So I don't understand why they decided to make a season finale of people lining up to take a swing at Sylar, while standing around chatting about what's going on. If I wanted that kind of action, I'd watch Naruto.
