I'm one of the biggest fans of the original and I was really hesitant to read that draft. (I sure hope that it IS a heavily-edited rough draft!) But I could not resist and read it anyway.
My first impression is that it is not going to be as genuinely creepy as the original. I feel like you could substitute the Creeper with a Pterodactyl or something. But there were definitely some cool moments in the script. Well, I haven't read any scripts before they have been filmed, so this is my first taste with something like it. In a way, it was thrilling to read a script of a film I've been anxiously waiting for.
