I fall more into the 'awful' camp than 'weird'. I like his writing, but the stupid, stupid dues ex machina supernatural bullshit he always cobbles together to tie everything up leave me hating the story more than I enjoyed it.
I would rather him leave his endings more ambiguous than 'oh, it was really an alien sent by God who fixed everything by wishing it back to normal' or whatever his end is on whatever book.
I agree with you to a point, though I don't feel it ruins the stories. When they do end that way (and it's often, but not always), I cope with it. I think he bases his writing off a premise and a cast, then kind of lets them work into a natural zenith in the problem, then introduces some new supernatural device to resolve it.
