I really liked this episode. When I read that it was going to be an episode about the past, I thought that it was going to be boring and that it wouldn't reveal something that we didn't already know. I was wrong.
Some of the episodes in Supernatural often reminds me of some other tv-show or movie. This time it was Back to the future with Michael J. Fox. Does anyone remember that movie?
I can't wait for the next episode!
