I don’t know whether this is an unpopular opinion or not but I actually think that the way Tasha Yar died gave the show much higher stakes throughout it’s entire run. Here is the chief security officer, main bridge crew, tragic back story, potential love interest for the robot character just slapped down by the monster of the week. It made all the subsequent dangerous situations seem much more dire because “they were willing to kill off someone in the main cast”. I also think that Yesterday’s Enterprise was an awesome send off for that character that let them have a heroic ending for her after all.
It was a shame because I think Denise Crosby could have been awesome as a recurring character and in my opinion, we didn’t get a great strong female character in the main cast (until DS9 which is an embarrassment of riches in that department). But I maintain that casually killing off Tasha Yar made my first watchthrough of TNG much more exciting.
I don’t however like the additional stretch of her half-romulan daughter. It’s pretty soap-opera-ish in my opinion and tarnishes the heroic sacrifice of her character.
Okay, but that’s not really what they did with Sela.
Sela wasn’t ‘Tasha returned’ - she had nothing in common with Tasha (in terms of personality or her role in the show) except for being played by the same actress. She clearly wasn’t just a backdoor soap opera route for Tasha to return.
Also she was only actually in four episodes (on the first of which the character wasn’t identified and Denise Crosby was an uncredited voice only). Sela’s brief appearances were so memorable that we tend to forget how minor her role actually was across the span of TNG - Tomalak had a bigger role, for example.
Definitely all true. But the implication that she was made into a Romulan love slave, especially after having established her backstory always rubbed me the wrong way.
