You really can feel how much she thought:
Thats it, my career ends in a jumpsuit.
I think she just hated Star Trek and tryed to make something really good out of it. But I am afraid, that the whole concept of Voyager had no room for a great actress like her. It was a show with 2 dimensional characters in 2 dimensional conflicts. Thats why her whole way of acting looks so much out of place.
