Summerslam 2015
This was a terrible year, except for 3 incredible matches that single handily put it on this list! No one will ever forget The Undertaker returning to get revenge by defeating Brock Lesnar with a low blow and then putting him to sleep.
A hidden gem on this night was Cesaro and Kevin Owens absolutely tearing the house down. Go back and watch this match right now! Cesaro and Owens showed WWE brass just how excellent they both could be if pushed properly.
Also, the WWE title match between champion Seth Rollins and challenger John Cena was an instant classic that proved how good both men are!
