Fanfiction: Writings about existing franchises

This book was a bit of let-down for me. Yes, it is very nicely written, characters are well described, they have even some (slight) development to them (which is rather rare in all fanfiction stories), but it feels like painting by numbers. Elizabeth and Gardiners travel all the way to the Lake District, so there is never a meeting at Pemberley, and Lydia is ruined (for long time it seems irrecoverably, but it turns out better). Then Elizabeth meets Darcy when she hides in London with her uncle and aunt and everything proceeds as you expect. Lydia is sent to Canada to be married and saving the fame of the Bennet family, D&E have their happily ever-after, Jane finds some replacement for Bingley, who in the end (with many rounds around) marries Georgiana. Everything is very predictable and it takes extraordinary time to get there (59 chapters). If you read one of stories like this, you probably shouldn’t bother.
