It has been a long time that a grand tournament made me await almost any match from the 4th round with excitement.
With the great champions Federer (who, fortunately, has not lost it)and Nadal, the dangerous Djokovic, the "old" battle horse Roddick, and aspiring and capable players like Murray, Tsonga, Simon, del Potro (yes, he got a lesson today), mens' tennis is in the best shape in years, if not decades. The last time the field was so full of exciting and competitive characters was in the late 80s/ early 90s (old Lendl, Becker, Edberg, young Agassi, Courier, young Sampras, Stich, Ivanisevic, young Chang).
Enjoy as long as it lasts (unfortunately ladies' tennis is not in good shape).
Yup I agree 100 % with you. don't listen the the sour grapes. There will always be people that think yesterday was better then today. Usually they are over 60 years old and prepare for death.
...But in MTF this rule seems not to hold....
