74 reviews came in, all positive ("fresh"), before someone dared to cast the first stone with number 75. That person was not Cole Smithy but rather Ed Power, who writes for the Irish Independent. In his review, Ed states that the film is "expected to stand for something bigger than itself", and laments that for being a superhero movie Black Panther (the character) doesn't get to do very many superhero things. He praised the production quality of the film, scored it a modest 3/5, and chose it to be "rotten". Basically, he called a spade a spade. He will surely not be the only critic to give the movie a negative review.
But that's all that needed to be done to open the floodgates. Immediately social media lit up with people decrying Ed Power as a "racist" and all the other usual terms, and now here we are with the same old song and dance we saw with Lady Bird's RT score except with racial undertones.
