I rate "The Naked And The Dead" as among the better of most 20th Century American novels I've read. Not sure I could call Mailer a genius, but I liked his style. Though he never saw battle himself, critics and vets alike praised the authenticity of his voice in that book. The story has great character sketches, a single WWII Pacific battle narrated by each character, and it dared to follow the arc all the way.
Down to the end which is always
"Fuck patriotism - We are ALL animals"
Very dark stuff, but entertainingly told.
On the other hand, he was a talk-show slut like Capote.
And Dick Cavett kicked his ass.
So....I dunno.....
R.I.P. Mailer
