I don't like the ending at all, though it's a bit less absurd given the nature of the feud. Gargano being more concerned with injuring Ciampa than winning the belt does fit the feud.
In the minority, but I kinda liked the ending. It fit the story of the characters quite well.
I wasn't that big a fan of the overall match though. There were lots of "holy ****" spots, but it just didn't flow all that well. A large part of that is the LMS stipulation itself, which I agree isn't that good.
