Same here, unfortunately. I’m going to reread the series one of these days and I intend to hunt down the original before that happens, though.
I’ve heard that it completely contradicts many of the major plot developments that come later. I’d like to read it also but more just out of curiosity. It’s the original version of the Stand that I’m interested in.
My understanding is that this isn’t really the case other than some mostly minor things, for example the original version making two antagonists unambiguously different characters when later on they’re both different names Randall Flagg goes by. It does weave in some things from later books (the nineteen stuff mainly) and changes some direct references to the book taking place in a post-apocalyptic future into references to “parallel world” versions of the same stuff that were used later on in the series.
Then again, I haven’t read the original, so I’m not entirely sure.
