This. Even my wife has commented more than once that Seven wasn't just there for the sex appeal, she was actually a great addition to the crew. Well written, well performed, with a surprising amount of pathos for such an unemotional character. To this day, the relationship between Seven and the Doctor is my daughter's favorite thing about Voyager.
Focusing on the catsuit definitely buries the lead.
Her sex appeal was certainly a very big part of her being added to the show, same as with Jolene Blalock.
What I think is amazing of both women, is that they took the opportunity and did something amazing with their roles. Both characters became much more than just sex appeal, and the writers quickly picked up on that and gave them some great stuff.
Both Seven and T'Pol are highlights, sometimes carriers, of their respective shows.
