The Janeway in the series is sexy as hell.
(The actress not so much now from what I saw on some new show promo).
I remember reading in one of the novels how Chackotay used to frequently do her on the engine room floor, and was thinking, why didn't the regular janeway get some from her 1st officer instead of having sex with holo characters?
I think that's sorta what makes her hot, other than physically- her half smile, high cheeck bones, perky breasts, nice eyes, hard bod, - a lot is her attitude. That she is seemingly uptight about sex. Also her being command is attractive, as well as her being seemingly unattainable due to that I guess. So it seems like she's always unwilling to just relax and smile n give in to her human nature. Maybe she doesn't seem like she'd be able to just have fun and w/o catching feelings for chako maybe for vice versa (or whoever). Or she just doesn't like casual sex. Who knows.
At least the mirror universe characters aren't stiff prudes. Lucky Chakotay.
Bottom line: any episode where Janeways got her jacket off is much more enjoyable to watch. I bet even the sexless Harry Kim would agree.
