She had a cruel fate, but at least her final death by trying to escape with her daughter is absolutely in character. I like Sela and I thing she could have been used in movies, but her disappearance is a typical problem with MALE AND FEMALE characters of TNG.And despite all the attempts to bring Tasha Yar and Denise Crosby back in a more positive light, the show still manages to crush whatever good things that were done with her character. Instead of dying a hero's death at the end of Yesterday's Enterprise, she was instead captured by the Romulans, got impregnated by one of them and gave birth to Sela, a character that the show will completely forget by her third official appearance. Totally worth it.
I think a part of the problem is people don't realise that TNG is an old show. It ended exactly twenty years ago. The perceptions have continued to evolve. In 2014, medicine and psychology are usual profession for women, it’s no more a fresh way to show empowered women on scree. What was the general situation of female characters in American movies and tv-shows between 1987 or 1994?I was 21 when TNG came out and I was encouraged to see women in responsible roles. It's easy now to dismiss Crusher as being "the mother" and being in what some people call a "stereotypical caring role" but it didn't seem like that to me at the time. Similarly with Yar. It was good to see a woman in the role of head of security. It felt empowering. I think a lot of people who weren't there at the time don't appreciate that the roles that the women of TNG had seemed forward thinking at that time. Even now I look at the show and don't really get the criticism.
Troi was a character at maximum level of feminity, but I don't think it would have been more interesting for audience to only have tomboys as female officers. At least, she also had the excuse of having been raised by a quite conservative aristocratic alien mother.
I like Pulaski, but she was definitely too much based on Bones. Perhaps the writers would have given her more originality if she had remained longer on the show. At least, her attitude clashed with the other main characters. She also clashed with her personal background: she wasn’t a widow, she wasn’t had a painful divorce (at least a difference with Bones), she didn’t sacrifice her love life to have a career, she was many time divorced and happy with that.
