The Spice Girls had a lot of hit singles, that doesnt make them great singers.
Fact is during Kirbys day artists would churn stuff out. Maybe not to the degree he did, but did he gain legendary status due to how good he was or how prominent he was? Prominence and popularity does not equate 100% to talent.
As for Wrightson, didnt say I didnt like his art, just said I dont give a shit about it because he never did anything I really cared about and his style doesnt appeal to me.
Kirby though I have never ever liked. Even as a kid, I thought his stuff looked terrible compared to other artists like Dick Dillin, Jim Aparo and Curt Swan, who were some of the first artists I was introduced to in American comics.
