They may have brought 7 in as a sex symbol but the character became far more than that thanks to the writing and excellent acting.
I couldn't agree more. I was very sceptical when they brought her in, but she proved to be a much more interesting character than Kes. The character Kes had great potential, but the writers just didn't seem to know what to do with her.
It's a pity though the writers didn't write more strong character shows for other characters such as Tuvok and Chakotay. In the end, I became a bit tired of all the episodes that focussed on Janeway and Seven.
