I really like Serena's play, and am hoping for her to win a GS this year... I used to get really cut up when she beat players I like, but now I don't mind cos she's just about one of them herself.
Only thing I don't like about her right now is the occasional 'boxer talk' in press conferences (although lots of other players are getting into it), but I guess if you don't appear confident you're gonna get slaughtered by press and on the court by players.
