Rainer Wolfcastle is fine as action hero McBain, but when he's not playing the character, the show never really seems sure what to do with him. A major problem with the character is that everything he does is extremely over the top with little insight into the real person. Whether he's an ultra macho spokesperson or an overweight has-been actor, it's all dialed up to eleven. From time to time he even randomly morphs into his on screen persona and swears revenge or threatens to kill someone. Wolfcastle is all over the place and it's seldom funny. Shearer does his best with the material and his accent has become one of the most recognizable and imitated voices of any supporting character. But unfortunately it seems there are only so many jokes you can make with a Schwarzenegger parody before the character gets old. Granted he did have a great scene in "Radioactive Man" when he is nearly killed by a vat of acid. But aside from "My eyes! The goggles do nothing!" how many of his non-McBain quotes do you really remember?
As a wrestling fan I've flown across the Atlantic for the last five years specifically to attend WrestleMania (28 and 30) as well as TNA, ROH, Evolve, Chikara and most recently PWG.
I may have a problem!
But if you're reading my work then you probably love wrestling too, so lets focus on that!
