I was trying to remember anything about Orton/Rollins. Had no memory of it. Then going to Wikipedia and looking at the card, I remember the awesome finish to that match.
Triple H-Sting. It's fine but it wasn't great. Sting was 50 or so so it shouldn't be expected to be 5 stars anyway. The match was held down by Hunter's ego and all the run-ins. Sure, it gets a crowd pop, but why would the NWO help Sting? I know they don't care about WCW booking logic, but that'd be like the Iron Sheik coming out to save Hulk Hogan in 2005.
Cena-Rusev was fun, kind of a throwback to Hogan era '80s. Cena from an entertaining wrestling standpoint was at his best in 2015 with this and the U.S. title challenges. Rusev's career has really gone downhill in contrast...
Undertaker-Wyatt, there was no thrill to the match. Bray Wyatt is just not as strong a heel as a person in his position should be now, and it was true at Mania last year. Keep in mind that Undertaker in the runup to WrestleMania last year literally DID NOTHING to build this match up. Not once did he appear on TV. Wyatt was talking to a rocking chair the month prior. WWE looks at their roster and wonders why no one can get over, this program is a good example why.
Reigns-Lesnar. Brock is the biggest star on the roster then and now. I've come to hate the Money in the Bank briefcase because it lends itself to 3-minute long title reigns which does no one any favors, but what Rollins did here is about the best use of it as far as shock unexpected value. Reigns has needed another year to get himself enough over to become the guy. I guess he's a little better. Instead of Brock he gets to beat Hunter.
