The only character on Enterprise I felt was interesting was Hoshi.
She was a beautiful woman that wasn't playing the role of tight spandex and leather catsuit type of sexy, she was just naturally beautiful and wore the same clothes as everyone else. They never tried to turn her character into the smoking hot woman bending and contorting her body like a female comic book character, or turning her into a sexy dominatrix.
Well, almost never --three cheers for the Mirror Universe!!!
