I loved Salem's Lot, Jeresulam's Lot, not so much Carrie, Shining, Thinner pretty much most up to Misery. That was pure Misery trying to get through it. I read m,ost of It, more or less as a joke - on myself. Lost all interest and respect for his writing.
And yes, he was never wired correctly. Ever see any interviews with him? Not sure if its an act or real, but after seeing aboutv 5 interviews over 15 or so years - I think its real.
But he's supposed to be a great neighbor and very generous to the local community.
