5 WWE SummerSlam endings that disappointed fans

4. The Brooklyn Screwjob (2015)

The Undertaker beat Brock Lesnar in a dodgy finish at the 2015 edition.

The Undertaker vs. Brock Lesnar at SummerSlam 2015 was touted as the rematch that was too big for WrestleMania. It was rare to see Undertaker around at a time that wasn't WrestleMania season, and his epic brawl with The Beast on Raw alone was enough to make fans excited for the encounter.

Truth be told, the match was actually pretty good, and far better than the brutal bout they contested a year and a half earlier at WrestleMania 30. They wasted no time in taking the fight to each other and the Brooklyn crowd was invested in the action the entire time.

But then came the fluky finish. Lesnar seemingly had the match won when he had Undertaker locked in the Kimura, but then the bell rang for no reason. A confused Lesnar was on the receiving end of a low blow from Undertaker, leading to the match being restarted and The Deadman forcing Lesnar to tap out.

I could explain in detail what actually happened and why, but the bottom line is that fans left the Barclays Center that night fairly frustrated with what they had just witnessed. And who can blame them?
