The Undertaker's streak means alot to the marks.. but for the fans that really appreciate and understand pro wrestling...it doesn't mean a damn thing.
I really hope HBK wins so I don't have to listen to this streak crap anymore. Appreciate the wrestlers for their performances (in the ring, out of the ring, on the mic) and less for their win/loss record that doesn't mean anything in the world of sports entertainment.
And now you are one of those guys who really understand pro-wrestling at is fullest? please, spare me the lecture.
If it doesn't mean anything then why bother to post in this topic?
Then in reality you don't care who wins or loses because you understand pro-wrestling and in that world all of them are winners just because?
Without wins/loss records this does not mean anything because even if it is scripted, it is based on that, if not championships does not mean crap either.
And please don't get me the "It is al scripted, it is not a real sport" because if that is your train of though then I don't know why you watch at all when everything produced to creat the feeling of it being real, other wise the feeling they try to recreate won't make sense at all.
The streak is a big deal just because one of the more succesful individuals and the only guys who has been around the company for almost 20 years keeps that at the Mayor event, and 3 of those matches has been for the title.
The Undertaker is not the only wrestler undefeated at Mania, Goldberg is undefeated at Mania but does anyone care? No because he was with the company barely a year. Sable is also undefeated at Wrestlemania and does anyone care or even remember? No, because she was not there for more 4 years and was nothing impressive to begin with.
The Undetaker has one if not the most successful gimicks of the WWE hand has being very popular for the whole game, almost 20 years and he is still very popular.
The streak is an acolade to his achivements and means a lot to his fans but also a lot o people who is not a fan of his.
It mean something you probably hate for what you posted, so it is big.
It means a lot, it is also a double edged sword, because like all you said it can become predictable but it also becoes bigger with every year that passes.
And to be quite honest, there has been so many rumors than before Wrestlemania comes, everyone marks it will end (except the year Mark Henry came around, none marked for him) and in the end because it doesn't everyone that said it will end says "Oh he won't, it was so predictable" that is really annoying.
If you don't believe me, look at news archives that rumor had it Orton would end it, Batista would end it, Edge would end it, Hell HBK was about to end it at some point and now since the career is on the line, even with rumors of HBK taking time off, they are saying he might end it anyway to retire next year.
The Streak means a lot to the wrestling world, good and bad, there are fans of it, and people that hates it (which seems to be your case) because it is huge, 17-0 is easy to say, but means that at leats for 17 years you have to have a damn match at Mania, meaning that at least you need to be relevant for 17 years, and to win it means that there are something coming your way since no win at Mania goes just into oblivion (only in the case of Goldberg because he was leaving), that is how much success it means and the Underker has been very successful because his path does not end at Wrestlemania, even he takes time off it continues during the year.
So the streak is a big deal, even if you don't want to acknowledge it, otherwise It would not have so many haters that will love to see it end, and later will try to find something as big to complain about.
