This is really the first time the brothers have a physical altercation that wasn't just a misunderstanding. That aspect of the episode is very well done...a lot of thematic weight in the 5th season comes from the family dynamics that were made crystal clear in this episode. Unfortunately, this great material is embedded in a clumsy ghost story that has a uninteresting villain and one very lazy means of providing exposition. There are classic scenes here but not a classic episode on the whole.
