Yup... IMHO the series went on just long enough. Much longer and Walter mould have jumped the proverbial shark.
Exactly. There just weren't any other places to take it, and going to what few options there might have been would have resulted in things just overstaying their welcome.
There's not too many TV shows that really need to stretch out an arc over more than 5-8 seasons. It just gets old. Breaking Bad had something of a shorter lifespan (mostly because the character did, but also because that kind of thing just is going to come to a head sooner rather than later), but more than 8 seasons just draws things out too much- too much cast turnover, too much history to haul around, too few new things to do that aren't gimmicky.
