Alright, I'll give this one a shot.
Best Guest Host: I'd have to go with the first one, Batista. The reason I have to go with him is that the majority of the guest hosts were more or less useless when it came to advancing the overall plot of the WWE story arcs. They had their little mini-plots and I guess that's what they were there for, but Batista's bit was much better. He's a wrestler, he already had an established story to play off of, and he was given a free reign for a bit of vengeance. What could be better for a wrestling show?
Worst Guest Host: Oh there are so many worthy candidates here. Jeremy Piven is near top of the list, not so much for him as that annoying Dr. What's-His-Face he brought along with him. The most satisfying part of the night was watching that twerp go flying. Flavor Flav is up there with horrible guest hosts, but that could be just because Flav himself annoys me. Buzz Aldrin really didn't add anything to the show, but at least he had the decency to stay out of most of it.
Continue or Not: Please end it. Particularly nowadays the celebs aren't adding anything worthwhile to the show. If they're gonna be there, at least let them be used on rare occasions and only use ones who actually have some connection to the business. I had no problem with the original Mickey Rourke, Mike Tyson, Floyd Mayweather, or even Mr. T storylines when they came, but not as a continuous gimmick with different ones each time.
