Not a good advert for tennis, all things considered.
One of the players couldn't be arsed, the other was cramping after about an hour, and they both couldn't stay on their feet for very long at all. Djokovic's behaviour doesn't befit a number one, and apparent ambassador for the sport at all well, but we can forgive him on this one occasion. I, for one, think he's coped well with being number one, and until now hasn't made any bad mistakes when it comes to maintaining the right kind of image.
The match itself was okay, but kinda low quality considering Djokovic wasn't playing at a good level at all. Dimitrov will be found out when he faces a top quality player who is on the court mentally, unlike Djokovic. It was great theatre though, loved the tie-breaks in particular.
Imo Djokovic's actions are good for the sport. Whilst his behaviour might not have been acceptable it has certainly created a lot of talk and heated debate.
