Most of the victims of the undefeated streak should remain as they were, but I did not agree with there being so many rematches. I also did not agree with Brock Lesnar being the one to end the streak. Kane getting a rematch, fine, while I still disagree with it. The story is there with their characters so it's fine. Michaels, also fine, due to Michaels' retirement story and trying to outdo their phenominal match from the year before. That's it though. Where were the streak opportunities for Sheamus, Chris Jericho, and John Cena? Granted we might still get Cena VS Taker but the streak is no longer there.
1. Brock should NOT have ended the Streak!
Worst possible candidate. Lesnar can be an evil heel monster no matter what he does, so giving one of the biggest heel pushes of a lifetime to someone who didn't need it was one of the most awful decisions the WWE has made in recent years. Out of the other streak victims.... Orton, Edge, and Punk would all have been better choices than Lesnar.
2. No Triple H rematches at 27 or 28.
The 2nd match wasn't needed, even though it did save Wrestlemania 27 from being the worst event in the brand's history. The 3rd match wasn't needed either, despite it being a memorable match due to everyone involved. Had WWE booked Nexus stronger, Barrett could have been the perfect opponent for Taker at 27. Heck, even with the issue of Nexus splitting into New Nexus and The Corre, Barrett could still have faced Taker instead of being in that pointless tag team match against Santino's APPLE stable. At 28 it could have gone to Jericho or Sheamus.
Those are the main two issues I have with the streak. It was mostly fine other than the way it ended and there being a few unnecessary rematches.
