"Supernatural" is one of the best TV shows I've ever watched. It is about two brothers, Sam and Dean, who are hunters. But they don't hunt
animals; they hunt creatures such as ghosts, vampires, demons, and more.
In my opinion, the best part of the series is from Season 2 to Season 4. The first season is only an introduction to the characters and creatures. In the second, third, and fourth seasons, they cross the country looking for clues of their father who has disappeared. From Season 5 on, the story just gets boring.
