I don't get the love for the Stunner or the misbelief that it could come out of nowhere. it was extremely choreographed move that was nothing more then a kick to a gut and then a jawbreaker, something people had done before and still do occassionally, only difference was Austin turning his back on the receiver before dropping to his ass. This was a move that succeeded because of the receiver selling it far more then the person performing the move.
The misconception of it coming out of nowhere is due to the fact that most of the time you saw it, it was Austin sneaking up on the back of the receiver, waiting until they turned or turning them around then double finger salute, gut kick, slow turn his back while grabbing head and then down on his ass and guy acts like Austin's shoulder was a trampoline flopping back and around like an idiot.
A much better version was the Osaka Street Cutter. Start with what looks like an inverted suplex to lift the receiver, but as he comes down over the shoulder, lands on feet and performer drops into the sitdown jawbreaker/stunner. Much more visually appealing and shows more ...technique? class? strength? then just a kick to the gut and dropping on your ass.
I hate to go all Mark Madden, but you understand we're talking about fake wrestling, right?
The entire point of the whole song and dance is to create a reaction. The Stunner did just that. I get that opinions are like A-holes, everyone has one and it is cool if that is your favorite move. But, throwing the Stunner under the bus is just being antagonistic for the sake of being antagonistic. No sane fan thinks thinks the Stunner sucks.
