The best episode of the season so far. "Turn on, Tune in, Drop Dead" could also be one of the best episodes of the whole series. This episode has one of the best written scripts CSI has seen in a very long time. I was hooked intensely from start to finish. Try as I might, I could not quite figure out just where this story was going. The fact that it was not at all predictable added to its appeal. What I also liked is how this episode is gounded in reality. The visions of the "victims" are rationally explained.
