You lose me on this part.
Using this logic, you can't believe a Hulk Hogan Leg Drop would be a finish. Nor do you believe Big Show punching someone in the face is a finish.
Any move can be a good finish if you build the move up as a finish.
I have to disagree. The People's Elbow was a finish. That is about as shit a finish as they came. Not every move can be a good finish no matter how you build it up.
That's why the WMD is a shit finish. Now I get that in kayfabe that Big Show is the biggest athlete in the world and he has big hands, so his punches should hurt more. That isn't my issue. My issue is that during matches Big Show will throw regular punches and they don't have the same effect. You can't use a move multiple times in a match, then use the same move and give it a fancy title and expect it to have a greater impact. Plus, how many guys in wrestling have been giants and punched people and it didn't knock them out? Undertaker and Kane never knocked anyone out with a single punch, Andre never did it, Khali would chop people so I guess that's in the same ballpark, Giant Gonzalez never did it. Braun can't do it. And Show didn't even use it his whole career. He had been punching guys in the face for years with no comparable effect. It didn't become the KO punch until '08.
And yeah, unpopular opinion, but Hogan's leg drop was a bad finisher. Hogan was fairly big, but it was his arms that got all the attention, never his legs. If he had meaty thick tree trunk legs, then the leg drop wouldn't have been as bad, but the move is only iconic because Hogan used it. Any finish Hogan used would have been iconic. Give anyone else of comparable size the leg drop and build it the same way Hogan built his up, and people wouldn't buy it. This isn't a criticism of his in ring style because even Hogan himself joked all he had were three punches and a leg drop. My criticism is that punching a guy three times after getting beat up for ten minutes, dropping with him a boot to the face or a body slam, and then dropping a leg on him isn't a good build.
And I'm not trying to ignore your point. If Bayley had some of amateur wrestling background then I think her finish would be more impactful, but no matter how you try to sell it or build to it, a move that 95% of the roster does isn't going to be a good finish, especially when legit power lifters and amateur wrestlers are doing it for two counts and some random lady is winning titles off it.
