<P> The performance received generally mixed review from critics, who complimented Beyoncé and Mars' part of the performance but were critical of Coldplay . Jon Caramanica of The New York Times stated that Coldplay "acted more as a stagehand than an actual performer" while Beyoncé's section of the performance was "the night's true event". Caramanica also noted that Beyoncé and Mars "outsang" Martin during the closing part of the performance . Andrew Barker of Variety similarly noted that "Coldplay seemed resigned to politely allowing themselves to be played right off their own stage" by the "far flashier" Mars and Beyoncé . In a review for Fox Sports, Chris Chase panned Coldplay's performance, calling it "inexplicable, indecipherable, and unnecessary" and a "musical snooze". Chase complimented Beyoncé's and Mars' appearances but described the performance as "boring". Alex Needham of The Guardian gave the performance four stars, saying that "Queen Bey at the height of her powers effortlessly overwhelmed Coldplay's widescreen anthems in a show that seemed lightweight until she showed up". </P> <P> Robert Bianco of USA Today stated that Martin "seemed overwhelmed" by the size of the event, and that despite being a "personable and energetic performer", an "awful lot" of Martin's energy "went into jumping". Bianco praised Beyoncé's appearance and stated that she "stole the show". Wendy Geller of Yahoo! also complimented Beyoncé's and Mars' appearances, but criticized the montage of previous halftime performances, describing it as "confusing rather than touching" and stating that the performance was "definitely a cold play". </P> <P> Following the performance, Beyoncé was criticized for performing a song that they considered to be "anti-police" during the halftime show and for appearing to align herself with the Black Lives Matter movement . Former New York City mayor Rudy Giuliani accused the performance of being anti-police and also criticized Beyoncé's use of Black Power and Black Panther Party symbolism in her dance routine . "This is football, not Hollywood, and I thought it was really outrageous that she used it as a platform to attack police officers who are the people who protect her and protect us, and keep us alive," he said . The controversy caused a "#BoycottBeyonce" hashtag on Twitter and protesters announced plans for an "anti-Beyoncé" rally on the morning of February 16 outside of the NFL's headquarters in New York City, but no one showed up for such a rally . CNN political commentator Sally Kohn stated that "too many police continue to show themselves to be far more interested in reactionary defensiveness and preserving the abusive status quo ." Black Lives Matter activist Melina Abdullah praised Beyoncé and other artists who "are willing to raise social consciousness and use their artistry to advance social justice ." </P> <P> The halftime show became the fourth highest ever watched show in the United States, with total viewership of 115.5 million . </P>
