Supernatural is something different. It is not just a Tv series. Only 1 episode is left and I really don't know how to say goodbye to family. I don't know it does the same effect if you binge watch all 15 seasons in a short period. Even if some seasons were underwhelming, you can't quit them. There is a special bond I've never witnessed for another series. Supernatural is and will always be a legend. It may be a horror series but it is also one of the most funny tv series ever. Btw, imho first season is their worst season, be patient and continue to watch it. It will blossom like a supernatural flower.
