Don't feel bad, I think for the most part it seems to suck everywhere around the world. VERY few exceptions.
I think it is exceptionally bad on the Canadian networks. There are usually two commentators. One of them actually knows something about tennis, the other guy knows nothing (Vic Rauter), he does commentary for F1 and soccer as well. So the whole time Vic Rauter is asking silly questions about tennis that most fans should already know. The whole broadcast presents tennis as a very foreigner sport to Canadians.
