It is one of the best shows I have seen so far. Honestly, it is a ride full of emotions. And what makes this show great apart from a strong plot are the flawed characters. The characters are so perfectly imperfect that we start to begin to relate to the decisions they make. obviously, the wayward brother duo of Sam and Dean will force you to think about what is right and what is not.
Even if we ignore everything, it is an entertaining show to watch.
