my favorite is clearly either Vince McMahon or Eric Bischoff, both had GREAT heat and both were Authority figures who got under your skin, also Mick Foley as Commish was another favorite of mine. those were my top 3 with an honorable mention to Vickie Guerrero as i just laugh at how she gets so much heat. all she has to do is say two words and the fans boo insanely loud.
the worst was the anonymous GM and only because they didnt finish the storyline. a story is not a good story if it doesnt have an ending and this story had no ending. who was the GM???? Cole? Laurinitius?? McMahon in an odd way?? JBL??? Stone Cold??? Foley?? that's the problem. it left you guessing, but in the end, it wasnt revealed and it took a while for the gm to say something because Cole had to say his lines which took up time while the other GMs/owners/commishs just come out and talk, really the computer was the only one i really disliked (not counting the celebrity GMs) as the others had their strengths. really my only issue with Johnny is that his voice tends to give me a headache, but that's nitpicking, when his voice doesnt annoy me, what he says and does is entertaining and he reminds me of a lying politician.
