This was better than I expected...

I hope they make a Season 2.

I also liked the liberties they took with the appearance of Mary Winchester, Bobby, Jessica, Yellow-Eyed Demon, and John Winchester. They seem to work really well.

I don't know what age bracket this show was meant for in Japan, but I would have liked to see more of Dean's obsession with classic rock as well as his womanizing. That was an integral part of his character.

Everything I say is backed by science
