I loved John Laurinatis. Yeah, he was a little stiff and awkward, but the guy was easily the best heel GM/authority figure we'd had in years. I mean, not only was he an absolute laugh-riot -- the whole "Mr. Excitement" thing was golden -- but he knew how to play his role very well, he was an absolute spineless weasel. People love to criticize him for forgetting his lines or stumbling with them, but he's certainly not the only one who ever made that type of a mistake. Other than that, he performed at a really high level. His relationships with Cena and Punk made for compelling possibilities, not to mention that he had his own little "stable" of supporters in Otunga, Eve, and Big Show. Big Johnny actually made some of those people more interesting than they really were.
The thing I'll miss most about him is his willingness to do whatever it takes, though. He willingly looked like a jackass every week, so that the fans had someone to laugh at. He was a bumbling coward, but he played the role to perfection. Johnny Ace was the perfect "puppet" for upper management and he went out there and did an awesome job every week. This guy was EASILY the number one heel in the company when he was around and it's just a shame it couldn't have lasted a little longer, or at the very least, been a more conclusive ending to his reign.
