Whenever icons arise there will always be a large segment of people who dismiss or trivialize them. Think about the way a looooot of white people loved making fun of Michael Jackson for years. Not even white-face MJ, I'm talking even during Thriller era. Someone is always going to say the new icon isn't as talented or good as the old one. Hell I remember when I was a kid and adults said Jordan was selfish, overrated, didn't know how to shoot etc. Now those same people will tell you Jordan was the greatest of the great while arguing LeBron James is...selfish, overrated, doesn't know how to shoot etc.
I'm not a "Beyonce fan" but can recognize her greatness. I liked much of her last album too.
