It's only natural to want to see your favorites performing to the best of their abilities- win or lose. The losses are difficult, but what's most difficult to watch is Serena struggle against herself. This isn't the main boards so I can say we all know the match would have had a much different complexion had Serena showed up. Sometimes when you want something really bad you put too much pressure on yourself, which might explain why Serena looked so rushed from start to finish. I could feel how tense she was after the first couple of games. The only time she actually looked relaxed was after the match (trophy presentation).
As bad as 'other' fans can be, I think that sometimes us as (Serena) fans can actually be more harsh- but it's just because we know the pottential is conflicting with the results.
Let's not forget about Serena's year so far:
-Hasn't played and lost before the QFs all year
-In her last 4 events has only lost once before the Semi-Finals (two consecutive Finals)
-Has won 10 out of her last 11 hardcourt matches this year
-She has a winning record against the current top 10 (wta ranked) players she's faced this year, winning 6 out of 10 of those meetings this year.
-Has played 2 grandslams reaching the QFs of her first (in over 6 months) and the Finals of Wimby beating the highest ranked player in her draw
-Depending on how she fares at the US Open, she could potentially have the best 3 consecutive Grand Slam record this year....QF, F, ?
-She's only lost to the best players of the year, no losses to anyone ranked below 20 on the Porshce Race Standings and only once to a player ranked outside of the top 10 (Petrova)
-Has only lost to two players ranked below her on the current Race standings
