If you're talking about his 2015 era where he was an absolute grind bot then yes, it was a bit boring. 2011 Djokovic was entertaining to watch because he was pummeling the ball from both wings, better than anyone else had done at the time.
Ever since 2018/2019, he has become one of the most craftiest shotmakers on tour to compensate for his degressed baseline play. It's a bit of mockery but he plays more and more like Federer as he ages is the simplest way I can put it.
