"I wouldn't read Joseph Conrad if you paid me-way overrated in my opinion. Does anyone read him for pure pleasure??"
I do 
"I love George Orwell but he is basically an excellent journalist more than a writer."
He is a pretty good writer imho. Although written a long time ago, his writing style in 1984 does not date, unlike Nevil Shute's utterly boring and superficial 'style' of implausible dialogue, incredibly superficial prose, and casual sexism.
"Neville Shute (who wrote On The Beach) was a mediocre writer who thought up great plots- fab plots."
I don't remember On The Beach as having anywhere near a great plot, let alone a fab one. It was the completely unrealistic, laughable story of how people would NOT behave when faced with annihilation - not trying to save their lives by moving down south, talking about whether to start fishing season a bit early this year and decide not to (as if there will be a next year, ffs), one guy's wife is concerned about his career (although they are all going to die soon) and shouldn't refuse an assignment, which would take him away from his wife & newborn baby for months so they die alone. What? 
An example:
They are talking about a couple and this woman says "I hope they get married and have children". When told how unlikely that is with, you know, certain death by September , she replies:
" Oh dear, I keep forgetting. "
Well, you deserve to die if you're that stupid, don't you? 
(Sorry, remembering that book always gets a rise out of me.)
