Is the current state of men's tennis completely boring? Not totally, there's still some entertaining players to watch, but I can see how the dominance of the top 4 in the last 6 years can be boring for some. I would love to see Tsonga, Del Potro, Wawrinka, Gasquet win GS finals, but it just isn't happening. Courts being slowed down surely doesn't help they're case, but it's not the only reason they can't bring they're game to another level.
The way the game is thought nowadays and has been for the last few years is also why most players adopt the same style, aka defensive baseliner. If you look at what is being teached in the tennis schools aka baseline top spinner, it's hardly a surprise that youngsters all play the same. These kids are thought to hit top spin shots from the baseline and not get away from there because they will otherwise be passed. I recall playing a few juniors last year and most of them struggled when given low bouncing slices and looking foolish when being brought to the net. They also were pretty much identical clones of each other, tennis wise. If we're going to see more entertaining tennis, this has to change.
The only redeeming factor in today's game for me is Roger Federer. He can still win a slam imo and he does make the match up with the grinders a lot more interesting due to contrasting style. When the day comes and he decides to hang the racquet for good, it's quite possible that I will lose interest in Tennis. There's only so much grindfest that I can stand watching, having to go through this all the time will be too boring.
let's be patient, that time will come soon
