I am an avid cm fan, and I thought this was one of the best shows they ever did. It was the most disturbing one I've seen, making it great television. I don't like those shows where you know what's gonna happen, the bad guys get caught, people are saved, good guys win.
This episode was shocking as the girl's dad was actually killed; didn't see that one coming. The "night stalker" was ruthless and the emotions the show brought out in seeing all the death, dispare, and wonder is a rarity in television shows today. I'm just surprised so many people weren't happy with it. I thought it was brilliant. Way to go, cm!
