well, some of these are good examples, but some of you are missing the point, such as the batista and edge haters, to dislike someone doesn't mean their reign wasn't good
a couple of good examples
undertakers first title reign which he lost 2 days later back to hogan...bad
agree with kane's 1 day run, terrible, don't know why he hasn't gotten it again in all this time
but i think the worst of all time was the ultimate warriors title run after wrestlemania 6 till he lost it to slaughter, this guy was suppose to be the next thing in wrestling and i think not only the fans but the company realized at that point that he couldn't carry the load, best thing they ever did was get that belt off him and put it on slaughter, only to have ol' reliable hogan get it back again
as for slaughter being a terrible title run? how can that be possible, he had so much heat it was unbelievable, they had to change venues for wrestlemania 7 because of him and his character, i think for the time and that gulf war and his persona was golden, and anyone who took the title of the warrior was good in my books anyways, alot hype and not much delivery
