Selar was nice, if they even remotely fleshed out her character.
If you think about it, Vulcan characters in general are difficult to flesh out in a short time scale. And Doctor Selar wasn't exactly the main focus of the episode in which she appeared. T'Pol got a lot of attention up front, and it still took time for her to move beyond "standard Vulcan stereotype."
I like Bry Sinclair's idea of having her be Crusher's replacement in season two, instead of Pulaski. Generous opportunities to learn about her, and let her develop a personality.
