I really have to agree with this. I know that this guy is hating on Punk, because he does so everywhere else, but I've never believed the GTS looked legit. You get this guy on your shoulders, making everyone think you're gonna do some devastating slam or drop him on his head, but instead you shove him off over your head and knee him in the chin. The move seems to fall totally flat once that happens, in my eyes. I know that a knee in the face would actually hurt, but the move itself looks extremely fake and not painful at all.
then again, due to the nature of the stiff wrestling, Kenta's GTS looks seriously legit and extremely painful, Cm punk did a more stiff version of it in the ECW days, but I think maybe they tuned it down because of stuff like Rey mysterios nose and people not knowing how to receive it well
