#1 SummerSlam 2016

First of all, I want to make something very clear - Summerslam 2016 was not a great show by any means. In fact, Summerslam was a pretty average show that is easily the worst Summerslam in the last 5 years. However, the fact that WrestleMania 32 was a big, fat blunder means that even an average show like SS 2016 looks like a raw gem in front of it.
While an argument can be made that WWE was marred by a really bad injury phase during the WrestleMania period, the fact that there was only one match on the card that was considered great and all the marquee matches failed big times did not bode well for the overall. Plus, Summerslam had that one match, that one dream match that turned out to be the biggest difference between the show.
As has been the case with all WrestleMania's since, well, eternity, the night in Arlington ended with the first ailed coronation of Roman Reigns when he wrestled a horrible match with Triple H. Brock Lesnar's laziness turned a highly hyped fight with Dean Ambrose into a glorified squash and ,somehow, WWE felt that putting two 45+ competitors inside a Hell in a Cell for 30 minutes would be stunning idea. Well, it wasn't. It sucked.
Summerslam, on the whole, was just marginally above Summerslam. Lesnar's dream match with Randy Orton turned out to be another glorified squash, Ambrose's WWE Title defense surprisingly fell flat after a stunning build and an enraged crowd turned a fantastic match between Rollins and Balor into a average affair. It all came down to AJ Styles and John Cena to save the day in Brooklyn, who wrestled one of the best Summerslam encounters of all time to give the show an edge over its Big Brother in 2016.
