no its not ! wwe is regarded as sports entertainment, its entertainment based on a sport, ballet isnt a sport that is described as performance theatre but you do get sports that are practiced where the outcome is known !
Eg. gymnastics, it is practiced and repeated continuously with a know outcome, same applies to synchronised swimming the same can be said for any track based sport because they repeat the same thing over and over. if someone runs a 100 metre race he will start in a spot and 100 metres later end in a spot and that is a repeated action everytime he or she runs the 100metres (they will not run 99 metres or 101 metres.
it is not like football, tennis or rugby where the ball in play makes the outcome of the game or match unpredictable.
