Several of the critics noted the video 's approach to media , in which they assumed that the " Mr. Know It All " is an individual man . Brad Wete of '' Entertainment Weekly '' , remarked that " It ’s interesting how she used the video to kill two birds with one stone . The song itself is about a misinformed individual , but the clip takes a swipe at the media and blogosphere . Personally , I prefer more direct musical approaches — like Michael Jackson ’s " Tabloid Junkie . ” But Clarkson ’s song is cool . " VH1 remarked , " When we first heard Kelly Clarkson ‘ s latest single , “ Mr. Know It All , ” we figured that , thematically , it was a fairly straightforward kiss off to an ex that did her dirty . However , after watching the video for the song that debuted in the wee hours this morning , it ’s apparent that there ’s another target for her ire : The media . " adding , " However , it turns that it ’s not just old media that ’s got Kelly down . The blogs are on her case , too ! " and later concluding , " Whether you ’re a big music superstar or someone whose only exposure to the rumor mill comes courtesy of Facebook , gossip is unavoidable . How you choose to react to the haters , however , is entirely up to you . You can wallow in their nasty comment sections ( or op-ed pages ! ) , but at the end of the day , would n’t you rather go outside and see the sunshine ? Kelly Clarkson would , that ’s for sure . " ''Hollywood.com '' remarked " Clarkson puts a man ( whose face we never see ) in his place for thinking that he knows everything about her . While she 's a few unicorns and eccentric costumes shy of creating a Katy Perry or Lady Gaga experience , she brings enough sass and glamour to the video to make it worth watching . The lyrics itself are powerful , but her meaningful looks into the camera and bold demand for independence really help to drive the message home .
