10 Worst Main Events In WrestleMania History

10. John Cena Vs. The Rock (Wrestlemania XXIX)

WWE really should learn to leave well enough alone.

At WrestleMania XXVIII, the company drew its biggest buyrate of all time for the "Once in a Lifetime" showdown between The Rock and John Cena. The match, a year in the making, inspired debate and split the WWE fan base like they were teenage girls at a Twilight premiere. It was awesome, fun and created genuine anticipation for a dream match unlike anything WWE had seen in years.

The Rock won that match in his hometown of Miami, and the fans went home happy. There was no screwiness, no denying who won. The fans were promised an epic encounter and they got it.

Not so epic was the rematch the following year.

Hoping a second showdown between the Superstars would generate the buzz of the original, not to mention give Cena a chance to get his win back, the company booked the match on top in 2013. The result was decidedly lackluster as the performers rushed through the match, trading finishers just minutes in before an injury forced The Great One to slow things down.

By the time Cena delivered the Attitude Adjustment and won the match, fans were left underwhelmed and unimpressed by the followup, which was more Attack of the Clones than Empire Strikes Back.
