Supernatural comes to a close with a moving finale that feels familiar while still managing to be unexpected and suspenseful. Jensen Ackles, who plays Dean Winchester, and Jared Padalecki, who plays Sam Winchester, take a very good story and make a great series finale. Just as it was in the beginning of Supernatural, “Carry On” is a story of two brothers and what’s meaningful to them—saving people, hunting things, and family.
