I'm really disappointed that creators didn't catch on to this and design their shows to run for one or two seasons. Not everything needs to be a decade long odyssey, and in fact a great many TV shows that were great at first were IMO destroyed by trying to keep running for as long as possible, long past the point where they ran out of things to say.
