Nah, this is like saying you have to be a director to say a movie sucks.
I can’t draw a cat to save my life, but bad art is bad. There’s overdesigning, which you may or may not appreciate, and then there’s that Cap image and Liefeld’s lifetime avoidance of drawing feet. The guy can draw, but the weaknesses in his art are blatant, and funny as hell. He made lots of stuff people don’t mock because it’s actually good.
