I've read the original 'cut' version and there was a version out in the mid-80's, was it, that was touted as the 'uncut' or was it 'unabridged' version. Is there yet another version out that is actually more than the 'uncut' version, or is it basically the same but repackaged? Or has he rewritten and added parts?
Now I'm doubting my own memory
In any case I spent countless nights on the very first version I read and loved every minute of it. On a second reading (with what I'm now calling the Phantom edition) it was still good, but the ending sucked. Maybe that's because my tastes had changed more between the first and second readings. But on that second reading, I recall a massive sense of disappointment at the end. I only watched about half of the mini-series, which I wasn't too keen on, couldn't really compare to what I'd imagined.
If he has added more to this 'extended' edition I'd be very annoyed. Dean Koontz did a similar thing with Demon Seed awhile back, updated all the references and technology in the book. Ruined it as far as I'm concerned.
