#5 Shinsuke Nakamura vs. Jinder Mahal

Jinder Mahal's 170-day WWE Championship reign produced nothing of value besides his loss of the title to AJ Styles. Every other match was dreadful. Every segment stunk.
The feud with Shinsuke Nakamura proved to us that the vaunted King of Strong Style can't just be stuck in the ring with anyone and be expected to carry the show. A stinker of a showing at SummerSlam and an only marginally better match at Hell in a Cell proved it.
Inexplicably, there was also a lot of promo work in this feud. Take Shinsuke Nakamura, whose English is fine but whose accent can make him hard to understand, and Jinder Mahal, who is quite bad on the mic, and have them do promos, and you don't have a recipe for success. The feud reached its nadir during the infamous Mr Miyagi promo, where WWE had to come out with statements to erase the bad PR it generated.
Through all of it, Shinsuke Nakamura went nowhere, beating John Cena and Randy Orton clean only to lose to the worst WWE Champion of the modern era...twice. If he is to be involved in a WWE Championship match with AJ Styles at WrestleMania, the company will have to do its best to heat him up in the coming months, to make him a believable Royal Rumble winner.
