Personally, I always thought that Big Show/Giant was never booked properly. The only time I really liked the way he was booked was when the WWE first put Big Show on the WWECW roster. That was when Paul Heyman was still around, and they booked Show as an "unstoppable" monster (and/or Giant).
In "real life", who could really pin Big Show unless he allowed it to happen? A guy that big shouldn't be jobbing to guys who are smaller than him (at least IMHO). I think the idea has passed it's prime by now, but booking Big Show as an unstoppable monster-heel should have been priority number one for every promotion he worked for (WCW and WWF/E). I don't know if a undefeated streak was necessarily the answer when Paul Wight first debuted for the WWF, but it certainly would have worked better than what they did. I think both WCW and the WWF/E dropped the ball with such an impressive physical specimen they had as an employee (that impressive physical specimen being Big Show/Giant/Paul Wight).
Who knows, though? Maybe Big Show/Giant didn't want to be the center of attention on the show...I can't see why he wouldn't have wanted to be, I know he said he told Eric Bischoff (when he was still working for WCW) that he wanted to make more money. I know he wanted to be more "over" with the crowd, so maybe that's not it at all. Like I said before, I think both WCW and the WWF/E dropped the ball with him, when he was younger. Now I believe it's far too late to build him up as a credible monster. Then again, it worked when Paul Heyman did it when he debuted with WWECW -- so who knows?
Like I said earlier, who's really going to be able to beat up Paul Wight enough to pin him for a full three seconds (in "real life")? Then again, this is pro-wrestling...not MMA, boxing, or "real life". I know all the endings to the matches are fixed, but it just never seemed "real" to see Big Show/Giant being pinned by a wrestler who was smaller than him. Just my two cents.
