Theres 0 possibility of that.
Whatever was in that "manuscript" could easily be replicated, if it was the main story and ending, the Director knows what they are since he wrote them. And if it was anything other than that, than it would have no effect on the shows story.
It's just a bad ending,nothing more. The rest of the show was good fun with good characteres, good concepts, some fantastic moments, but the ending blew. Thats all there is to it.
