Most likely due to the fact that Most people probably can't name two of Said critics without researching them, and people Know who Elvis is around the world and he's still cranking out hits in some countries with the old stuff. Including recently with the "horrible" Movie Music
Elvis has become an easy target for some of them because they think we fans are all crazy. Which if true it would be unwise for them to keep angering the Crazy folk, so who's really the crazy here?
I've never heard of John McCormick either Maurice, maybe next time I have online time to kill I'll do some research.
