No Spoiler Story-line: Sam and Dean are 2 brothers who battle the Monster of the Week and win.
Nice story technique: Sam’s flashback seems like spacing out and going to a better place in his memory, but it ends up helping in the moment.
Maybe a spoiler but certainly not a surprise: The gods coming to life are not, in fact, here to help humanity. *gasp* They are here to grab power for themselves.
Maybe a spoiler and actually a surprise: Given the facts of the TV show, I was surprised when the opening character, a man of color, survived the first chapter. In TV-land, non-white non-males usually get fridged.
