I don't know... I mean, seasons 6 and 7 of Buffy, I could have done without, so maybe he should have stopped at five for that show. Then again, for Angel, I would have been happy if he had skipped season 4 entirely. Dollhouse, I've never watched, so I can have no opinion thereon.

I think Firefly could have gone for quite some time, though. *sigh*
