And it pretty much worked. Lots of TVs got tuned to UPN to check out Jeri Ryan's tertiary adjunct.

And stayed tuned to UPN because Seven of Nine finally made the show work. She serves as a perfect foil for Janeway as well as that Pinocchio character that explores the human condition from the outside in, in the grand tradition of Spock and Data. And Jeri Ryan turned in 4 seasons of amazing performances in the role. All while vacuum packed from neck to ankles in silver vinyl.

Now Enterprise...it's pretty obvious they tried to make that lightning strike twice with T'Pol but Jolene Blalock had some pretty big stilettos to fill and I don't think she nor the writers really pulled it off. They of course ratcheted up the fanservice not only with T'Pol but with half the principal cast; Hoshi ended up pointlessly topless in one scene and Trip and Mayweather ended up in the decontamination chamber as often as T'Pol did. It was just generally a thirstier show, and that's not the only thing about it that just didn't work.
