Really great episode in terms of the writing for me and really getting into the characters. A lot of these ghosts stories get repeated so often they are redundant, but here they actually did take a step back and guided viewers through the whole ghost process and how they become ghosts, and how they become bad. Usually they just skip the whole transformation process, but that's what made it stick it out. Obviously to since Bobby was a big part of the episode it had to be that done that way. I think they really did it well.
Sadly it appears that there won't be a good end here for Bobby...
Still it was very good.
Solid delivery by the cast. The guy who played Whitman was good too. The effects were great too.
