Top of the list is obviously Big Show. First of all he's horrible in the ring, and can barely throw regular punches, never mind a knockout one. It's always executed slowly, sloppily and looks ridiculous. Besides, how many punches are thrown in the course of a wrestling match...why not just do it right off the bat. What happened to that cobra clutch/backbreaker throw he used in ECW?
As said, MVP's overdrive is terrible. Drive By should be his finisher.
Cody's finisher is also extremely generic. We have definitely entered the age of spinning neckbreaker finishers and Cody's Cross Rhoades is no different.
Bring back Burchill's Curb Stomp.... the jackhammer isn't working for him. And he's never consistent of whether it's a jackhammer or brainbuster.
You guys don't like Regal's finishers? Really?
Miz's Skull Crushing Finale is also a bit blah. It's not too bad but I preferred the reality check.
Punk's GTS is bad ass...IMO, one of the most painful looking finishers in WWE...next to maybe the Code Breaker. Cmon...being thrown off someone's shoulders and getting a knee right in the face?
Oh and LMAO @ Henry's World's Strongest Slam....what a lazy, boring, bullshit finisher.
Off topic a little bit...but Drew's finisher is fucking brutal.
