I'll have to concur with the majority opinion up above that the William's sisters are butt-ass UGLy! Whoopi Goldberg would be a fitting grandmother for the two of 'em.
BUT,.....back to the subject at hand: First of all, it's WOMEN's tennis and not MENs that makes it soooooooooo much better. In women's tennis you'll actually see a lot of volleys that take place whereas men, it usually doesn't make it over the net more than 3-4 times. The "serving" aspect plays such a bigger role in men's tennis that makes for a pretty boring match. If I "do" watch a particular tennis match, I like to see an average amount of groundstrokes b/t the two competitors, and you rarely see that anymore from the men. Nowadays, the men's serves have become so damn accurate and fast, that you rarely see good volleys between the two competitors.
Although not in this case, I generally prefer to watch men's sporting events vs. womens.
