The ending and the willing suspension of disbelief

So... I feel it is safe to talk about the ending now, hopefully. I feel that the ending, with the enforced seperation of Lyra and Will, is really where the reader has to create a personal framework which to suspend disbelief from. The first reaction I had to this seperation was anger but thinking back throughout the trilogy it had to happen and nothing I can do can re-enuite them. This seperation is a must, the novel basically teaches the reader about Lyra's movement from innocence to experience and how as an adult she has to make certain choices and because of this 'experience' she can no longer be with Will. These personal stories, or framework as mentioned above, are an interesting insight into where Pullman might go or really where anyone might go with there own willing suspension of disbelief. By this I am referring to the fan fiction located on various His Dark Materials fan websites across the internet. It seems that a lot of people were mad at the ending and created a new ending, yet we know this can't happen, which I would say to my delight many fans realized and wrote somewhat of a continuation of the end of the trilogy; this was a nice insight into what Pullman does for people and how individual people create their suspension. These fan factions delve into the world, giving fictional recollections of things like the adventures of Will and Lyra's daemons after their seperation from the children before entering the land of the dead, or how Will and Lyra are still so young with pretty much there entire lives ahead of them a great deal of post trilogy fiction sheds light on there possible roads of travel. I find all of these things interesting because as Pullman says "the aim of writing is to delight" and he must really be delighting people because the responses to his trilogy are phenomenal; inspiring people of all ages to write, and not write because they have to, but just to write and suspend their own disbeliefs to create something that will force the reader of their own writing to do the same, to suspend, which starts the cycle of endless imagination.
