She's always been sexualised as a reward for the presumed heterosexual adolescent male 80's gamer who completed the game fast enough and got the treat of seeing her strip down to her pixalated underwear.
So it's not inconsistent, although personally I always disliked that aspect of the earlier games. It cheapened the badassness of the character and seemed almost as out of place as saying 'Neh' to Shodan.
I don't think you can call an individual game sexist for having a sexualised character, but collectively the overall poor representation of women in videogames (Compared to male representation) is sexist... At least she's not Princess Peach.
