I think a good match would be one that goes on for awhile and showcases a massive arsenal of different moves from both competitors. High spots, for me, usually make a match(to me). It shows their desperation and desire to win the match so they are willing to sacrifice their own bodies to achieve it. However, I think the crowd should be a factor in what would determine a great match. It makes the moves sound so much better when they are trailed by a collective "OOHHH!" or random cheer from the crowd.
