Honest to goodness I hope this is it. They wrapped everything up perfectly but left a bit just to keep the world open and the mystery alive, to show that "it" was still there.
Unless it's written and directed by the same people, I wouldn't want another season. If so, and they have a great story such as this one, then absolutely. I just don't see that happening with how perfectly woven and straight to the point this series was. There wasn't a single second of filler or nonsense. Of course with something this great the want is for more but...there's no way it'd touch this kind of beauty. ESPECIALLY if the director(s, in this case) are/is different as well as the writers, I cannot stress that part enough.
