Supernatural

The shows on this list are all great in their own way, but none have the same longevity as Supernatural. There have been plenty of ups and downs over its twelve years, but even now fans are entertained by its latest content. Part of its long life is undoubtedly due to its simple yet character-based nature. A mix of fantasy and horror, Supernatural follows brothers Sam and Dean as they hunt the supernatural and follow in their father's footsteps. However, thanks to the perfect casting of Jared Padalecki and Jensen Ackles, it's as much about the character's demons as physical ones. Despite Sam's unusual ability of telekinesis, he wants a simple life, away from danger. With consistent conflict between the brothers, shapeshifters, vampires, and even gods, the show has incredible characterization and never a dull moment.
