This episode was just great. I won't write any spoilers so this will be spoiler free. This episode takes place in the view of "Baby" Dean and Sam's car. And it was just great. Each episode has action pact fights but this was way more chill. This episode made me think of the first few seasons when they just hunted monsters. This episode had great dialogue between the brothers and I loved every second of it. You may think it's going to be boring because it's always in the car but it isn't. This is what I missed and I love they did it again. Best episode of the season and one of the better Supernatural episodes ever. It's a must watch.
