This one is just bizarre.
The beginning of the end for Charlie's Angels really.
Ratings were already going down, I believe, and then they come up with this - ghosts and the supernatural introduced, about as far removed from the original gritty angels as you can get. Struggling to define Shelley Hack's Tiffany's personality, the writers now suddenly give her a background as a psychic with special powers, who organized seances at high school, was 'very big into the occult', and worked for a ghost hunter.
And then at the end of the episode, in the Townshend office, when Bosley expresses cynicism towards the existence of ghosts his desk rises and shakes - so ghosts do exist in the world of Charlie Angels, and we're moving into The Exorcist/ horror genre here, rather than three female detectives chasing criminals in downtown LA.
This episode concentrates on Tiffany (Shelley Hack), with Kris (Cheryl Ladd) and Kelly (Jaclyn Smith) on the periphery, and, as attractive as she is, it exposes Shelley Hack's lack of acting skills.
At this point Charlie's Angels is now badly missing Kate Jackson, who, if she watched it at the time, would have been on no doubt that she made the right decision by leaving when she did.
