Janeway was in my opinion a failure even in concept. Let's make a female captain but make her behave and talk like a man in some cheezy 80's action flick.
And my guess is most of the writers were men.
The members of "Monty Python's Flying Circus" admitted it was tough to write for women's parts. Jerry Seinfeld said his biggest challenge in writing was writing for Elaine until he decided to just write her like all the rest. On the other hand, in the 1970s, Mary Kay Place wrote a lot of TV episodes centered around multi-dimensional and strong female characters for shows like "M*A*S*H", "Mary Tyler Moore", and her own, "Mary Hartman, Mary Hartman".
Maybe sometimes it does take a "woman's touch."
