Review of O Brother, Where Art Thou?

I'm a die-hard Supernatural fan but this episode was worse than just not worth watching. The entire story would have been better set into a more detailed plot but instead of a good script creating believable characters, the director just has the camera pointed at the actor's faces, requiring the audience to use imagination to fill in all the missing details in this empty story. I like the Supernatural series and know all the characters but I need a story with at least a little depth to it. The whole episode was worse than merely a waste of the resources of the actors and the technology that went into the depiction; this episode completely broke the thread of good story telling that preceded it. I believe this weak link in this season's story arc will disrupt the line so much that it may be impossible to recover interest even with a well written follow-up story. Hopefully this sort of carelessly weak writing will not become commonplace or it may be the doom of this long running series.
