Star Trek: TNG - Season 2 Dec 4

[TLOE]

From what I understand, McFadden left because one of the producers was sexually harassing her. If I recall correctly, Stewart asked her to come back after the producer left the show and she agreed. To be honest, I preferred Diana Muldaur's character (and her as an actress) and kinda wish she had stayed on. Pulaski was mostly an attempt at placing a McCoy-like doctor on board, but even so she was a stronger personality. I feel Crusher was probably the weakest of the main cast in terms of character development or relative interest. I know this goes against how most fans feel about it, but it's just my opinion.
