Supernatural

Just finished the first five seasons. Great storyline and everything wrapped up. It looks very much like the first two were standalone, then the next three were the sequel. I read up on it and the original creator only intended to do five seasons. I suspect the next 3 seasons won't be able to top it, but I hope they can do better than just jumping the shark.

So, should I continue, or just leave it here?
