This really did not need to be in a cell. When I think of great cell matches I think of HBK vs Taker or Taker vs Mankind. This was not even close to that. This could have been a regular steel cage match. The cell meant nothing. There was very little drama. Taker takes some chair shots and then HBK is asking him if he wants to give up? I'm a huge HBK mark, but his involvement didn't seem necessary either. This was nowhere close to a great HIAC match.
Because both The Undertaker and Triple H helped define what the Hell in a Cell means and is today. And no, they didn't need to bleed to get over what they needed to, all they needed was a ring and a platform to tell what was an amazing story. Unless you understand wrestling, you don't get it, and I'm afraid you simply don't get it.
This match was never going to be two guys going out there to throw one another off the cell, it was made pretty clear before the match that both men respected one another and that the story that needed to be told was that neither wanted to give up, they are the "last of a dying breed", which means they are the final two guys from their era and neither wish nor want to give up, but after what has been a four year story, it has.
Shawn needed to be in there because he was what portrayed the emotion in the match. He didn't want to see Triple H destroy Undertaker, but he wanted to see the Streak end, as the match went on he was becoming distressed because both guys took a legitimate beating. Triple H was legitimately cut above the eye, it wasn't a cheap blade across the forehead, it was him actually being cut. Undertaker's back was bruised and in ribbons, by the end you could see they were in actual pain. You missed the entire point of the match, you missed the entire story.
If you grew up watching them you'd understand. I don't know or care what era you grew up watching, but whether you watched them since you were a kid or not, you obviously don't understand the entire point of story telling in professional wrestling and you don't understand why the match happened, sorry pal.
