As someone before me said this is the best episode of the entire series. The first time I saw it I thought it was decent. I enjoy the show because it's kind of mindless and you don't have to stare at it and think. It's light and fun but this episode will draw you in. The spoiler at the end will blow your mind. I try not to guess Mysteries because that's part of the fun, but the reveal got me and I consider myself a sophisticated viewer. It's definitely one of the best episodes of the entire season. Fun effects, fun ghosts, great plot. The previous episode is deleted and so make sure you don't miss it.
