WrestleMania 34 received mixed to positive reviews from fans and critics, with the world title matches being subjected to more negative responses.

[10] The four official theme songs for the event were "Celebrate", "New Orleans" (both by Kid Rock), "Let the Good Times Roll" (by Freddie King) and Devil by Shinedown.

As the 2018 men's Royal Rumble winner chose SmackDown's world championship, Lesnar's WrestleMania 34 opponent was determined through the Elimination Chamber match, which was won by Reigns.

Afterwards, Raw General Manager Kurt Angle scheduled The Miz to defend his championship against Bálor and Rollins in a triple threat match at WrestleMania.

[35] On the advice of Raw Commissioner Stephanie McMahon, Asuka postponed her decision[41][42] until both women's champions had defended their titles at Elimination Chamber[29] and Fastlane, respectively.

[31] The following week, Angle decided that Strowman would receive a Raw Tag Team Championship match at WrestleMania as long as he found a partner.

[33] At WrestleMania 31 in March 2015, then-UFC mixed martial artist Ronda Rousey appeared alongside The Rock and embarrassed The Authority (Triple H and his wife, Stephanie McMahon).

[19] She made some appearances over the next couple of years and was rumored to compete in the 2018 women's Royal Rumble match, however, Rousey denied that she would be at the event.

[47] Owens and Zayn continued their feud with Shane, including attacking him at Survivor Series[48] and Shane threatened to fire them if they lost their match at Clash of Champions,[49] while SmackDown General Manager Daniel Bryan seemingly favored the two by giving them WWE Championship opportunities at the Royal Rumble, when AJ Styles retained his title in a handicap match[35] and again at Fastlane, when Owens and Zayn were among the five challengers.

[52] In response, Bryan said he regretted favoring them and scheduled a tag team match featuring himself and Shane against Owens and Zayn, with the latter duo being rehired if they won.

[37] The following week, Orton was scheduled to defend the United States Championship in a triple threat match against Roode and Mahal at WrestleMania.

[46] The New Day earned another title shot at Fastlane in March, however, both teams were attacked by The Bludgeon Brothers (Harper and Rowan), injuring Jey, Kingston, and Woods.

[57] On the January 30 episode of 205 Live, new general manager Drake Maverick scheduled a 16-man single elimination tournament to crown a new WWE Cruiserweight Champion, culminating with the finals at WrestleMania 34.

[58] The tournament took place over the next several weeks, with Cedric Alexander and Mustafa Ali advancing to the finals at WrestleMania's pre show for the vacant title.

The match, originally named in honor of WWE Hall of Famer The Fabulous Moolah, was introduced to serve as a female counterpart to the annual André the Giant Memorial Battle Royal.

[33] On the final Raw before WrestleMania, Banks saved Bayley from a post-match ambush by Absolution's Sonya Deville and Mandy Rose.

[67] During the pre-show, it was shown that John Cena had indeed attended the event as a fan, and cameras followed him as he took his seat in the audience, a few rows back from the ring.

[68] The actual pay-per-view opened with The Miz defending the Intercontinental Championship against Seth Rollins and Finn Bálor in a triple threat match.

Nakamura kneeled down to present Styles with the WWE Championship, but then attacked him with a low blow and a Kinshasa on the floor, thus turning heel.

[69] In the penultimate match, Cesaro and Sheamus defended the Raw Tag Team Championship against Braun Strowman and a partner of his choosing.

[69] The match would perhaps end up being more notable due the majority of the crowd signaling their strong disinterest by chanting among other things "boring", "this is awful" and calling for then-former WWE wrestler CM Punk.

Cena-Undertaker left "fans stunned, bemused and feeling shortchanged at what had occurred", while finally the main event was a "slow-burning match" which was "a huge anti-climax".

For the other matches, Meltzer noted that the women's battle royal "was rushed through" and it was not the first of its kind at WrestleMania as promoted, pointing to a previous version in 2009.

Lastly, Needelman noted that Daniel Bryan, "perhaps the most popular wrestler of the past decade", "had the crowd in the palm of his hands" during his match.

[75] Troy L. Smith of Cleveland.com wrote, "In my mind, Lesnar-Reigns is one of the four worst WrestleMania main events ever, based on build, execution and immediate aftermath".

Smith also rated the main event as the "worst match of the night", but in contrast, he felt that the rest of WrestleMania 34 was "pretty great for most of its seven hours".

"[77] On the post-WrestleMania 34 episode of Raw, Commissioner Stephanie McMahon, with her arm in a brace, bragged about her WrestleMania performance, stating she knew that she would bring out the best in Ronda Rousey.

A four-team tournament to determine their opponents, called the Tag Team Eliminator, was won by André the Giant Memorial Battle Royal winner "Woken" Matt Hardy and Bray Wyatt.

[80] The Usos earned a SmackDown Tag Team Championship match against The Bludgeon Brothers at Greatest Royal Rumble by defeating The New Day.

[78][80] SmackDown Women's Champion Charlotte Flair commented on her WrestleMania match and future challengers, but was interrupted and attacked by NXT's The IIconics (Peyton Royce and Billie Kay).
