Yeah, even though there were some 5-Setters none of them felt (except for the ones above) like it's exciting. Many of the non-Top 16 seeds have been gone, meaning the "dark horses" are out and the favorites on paper had a good draw. I would say I enjoyed the drama of Monfils-Cuevas. That was crazy stuff.
There are always many very competitive, great matches at GS´s. One just needs to know what matches to pay attention to. The best matches are usually between a couple of lower ranked players. I rarely watch top players´ first two-three matches because they usually are boring as hell.
