I don't think the level of women's tennis would be where it is without Venus and Serena. Same thing happened when Navratilova came on the scene, then again with Graf and Big Babe tennis. The difference now is that there's two Williams, and for awhile they were dominating everything. It was interesting at first, having two sisters meet in the final of a Grand Slam, but after awhile the drama was gone and we expected them to get through, almost predictable. What's the point of watching if the early-round matches are all one-sided, and everything leads to an all-Williams final? They've been good for the game, definitely increased the interest level of the public, but variety and different styles of play will keep it going.
