Ever since Fringe has come back from the hiatus, I've been faced with a dilemma on Thursdays whether I should watch Fringe or Supernatural first. More often than not, I choose Fringe for the increased stakes a strong drive towards the end of the season. Supernatural, has been going through a rather listless Apocalypse this season, and while it has generally been stronger than Fringe, lacks the overall ambition and range of Fringe, often opting for those well-written but gimmicky episodes over episodes that really show how deadly the Apocalypse can be.
"Brown Betty" was, ostensibly, one of those episodes, almost filler-like in presenting an episode in story-form, somewhat relevant but not significant, revealing Walter's inner thoughts over the course of the episode. The story about a glass heart getting stolen was representative of Peter's heart getting broken and the reciprocal reaction from Walter. Personally, I liked seeing the outfits and the oft-kilter tone episode, but that was about it. The story didn't interest me nor did I care about the outcome. The good thing is that this is probably a one time deal.
The musical element of the episode was almost a side-thought with most of the characters getting about 30 seconds of singing. It was much more film noir than anything.
Score: 8.8/10
