Nowadays, you get to see endlessly long rallies. I'm not sure how that's supposed to excite me more. Maybe because I'm anticipating an unforced error to occur at any point or something like that.
Yeh, I also think it's shortsighted to make all courts play the way it allows for long rallies. It's not that I don't LIKE them - in fact, I do - but frankly, who would like to eat only chocolate all year long?
Tennis IS about variety, it's what makes it great. Narrowing it to its 'best' part doesn't make it better, it makes it poorer.
