"Dean is mysteriously transformed into a teenager. He has to deal with teenage struggles all over again, along with being a hunter."
This was a good episode. I think Dean should have stayed a kid, after all it got rid of the Mark of Cain. It proabably would have come back when he re-aged to the age he was when he got it, but still that would have bought him what? 15 to 20 years? Definitely would have been a good thing for him. Hell I'd love it if I could wake up back in my thirteen year old body. I'd view it like the girl in the story, a fresh start.
The kid that played young Dean did an excellent job. I really felt like I was watching the same character, just a younger version. I don't think I've ever seen that scenario so well done. If they could find an actor that could play a young Sam as well, then I'd say lets go with a prequel spin off. The young adventures of the Winchesters!
Really got a kick out of the whole Hansel and Gretal story. We even find out Hansel ate his sister with the witch, lol.
