Critical response
The tour received strong critical praise. Katie Hawthorne of The Guardian opined that "this dazzling spectacle feels almost like a one-woman variety show, were it not for the eight dancers, three singers, full band and mountain of glitter". She complimented Aguilera's voice, calling it "genuinely jaw-dropping", "rich", and "powerful". Una Mullally, an editor of The Irish Times, noted that "as Aguilera explodes on to the stage, her current energy is as fierce as her past legacy". Tim Heap, writing for the gay-themed magazine Attitude, commended on the show's setlist: "For every high-energy banger, from a reworked 'Genie in a Bottle' to a 'Candyman'/'I Want Candy' mash-up, there’s a ballad that really lets the vocals soar". He gave the tour a four stars rating, and added: "It’s not always easy to be a fan of Xtina, but when live performances are this good, it’s worth it". Katie Fitzpatrick from Manchester Evening News wrote that, "From the punchy pop of 'Ain’t No Other Man' to the bugle bop on 'Candyman', this is a flawless and full-throttle journey through Aguilera's career—and the costumes are fabulous". She also noted that The X Tour "delivers the razzmatazz" of the singer's Las Vegas residency. Helsingin Sanomat's Anton Vanha-Majamaa provided a positive review, and praised the tour for its feminist statements, intense theatricality, and rich choreography. He called Aguilera "one of the most important stars on the pop music scene". Metros reviewer Rishma Dosani, who attended the show at Wembley Arena, praised Aguilera for her emotional performance of "Beautiful". Writing for Express & Star, Kirsten Rawlins stated that The X Tour was "a beautiful show from start to end, filled with messages of self-love, peace, and female empowerment—mixed in with smoulderingly sexy costumes and dance moves." She also called Aguilera an artist of "exceptional talent, power, and humanity".
