Why is Doctor Pulaski (2nd season of TNG) almost universally disliked by Trek fans?
Three main reasons:share
General Replacement Scrappy effect (since she replaced the generally affable Dr. Crusher because Crusher’s actress had been fired for daring to object to showrunner Maurice Hurley’s sexual harassment).
Pulaski is written as a nasty, cruel, arrogant individual who picks on Data just as he becomes less irritating and more of a lovable, slightly child-like figure. It makes her come off as thin-skinned and abusive rather than as a wise Dr. McCoy figure.
Ever since people figured out that Maurice Hurley is a garbage human they’ve soured on his creative decisions, too.
