#2 Worst: Stale main event picture
Let's get this out of the way first. Owens, Zayn, Styles and Nakamura never disappoint when they're put in the main event spot. Every time they're thrust into the role, they deliver. Our only grouse is the lack of fresh faces, at the top of the card.
While RAW regaled us with unique matches like Asuka vs. Sasha Banks and Finn Balor vs. John Cena, we got another tag team match with the same pool of guys as always on SmackDown Live, once again. Not that they didn't deliver, because they did so in spades.
Throw in Randy Orton, and you've pretty much got a pool of superstars who have been mixed and matched in various permutations and combinations for the main event picture. The only notable break from the norm was when Bobby Roode won the US Title a couple of weeks ago.
