Ezri Dax and the case for fuller Star Trek characters

Ezri Dax's uncertain adjustment to becoming a host supplies one explanation for her unsettled portrayal on television. The books are preferred because they allow her time to settle and develop into a fuller character. A wider criticism is that a character becomes less convincing when one trait supplies the whole personality. The preferred Star Trek ideal is a crew whose members work together as professionals across their differences, with Uhura used as an example of identity that does not replace a professional role.
