As they shouldn't, he hasn't earned it. He took a dump on the face of the best talent on the roster and said "fuck you, I don't have to do SHIT but show up and pin you after you carry the entire program". Disrespect begets disrespect. Undertaker is a selfish, arrogant, broken down old has been who can't give it up, who doesn't give one shit about the next generation of stars and helping the company that made him thrive. It's always all about him.
Also, kayfabe-wise, why was that guy just sitting in his car in the middle of the parking lot? What's he waiting for? Either way, it made for a pretty entertaining ADR/Big Show segment.
Speaking of Del Rio, his match with Ziggler was great.
And Jack Swagger returning doesn't really do much for me. The guy can wrestle, but hopefully he improves on the mic. Could also get a new gimmick as well. Perhaps a heel coach character that forces faces to go through extraneous stuff like 100 pushups so that they get too tired to wrestle and lose a match or something. Just a thought.
