Well, for me it was not let down, and not to many others either. To be honest though for the first few hours after finishing the book I really, really hated it. But after that I slowly started to accept it.. and after some time I started to like it, very much actually. Well, SK himself said that "he too wasn't too happy with the ending, but it was the right ending." or something like that. Besides, it is the journey that matters. *shudder* We shouldn't be so... greedy when the ending came. SK - that damn bastard - gave us choice in Coda. Great choice, since he surely knew that no one would stop reading, even after his warning
Fanbase seems to split. 50 % hates the ending, 40 % loves it, 10 % thinks that "it's ok".
Or so it was. Nowadays I think that is purely 50-50, or 40-50-10
Sorry OT
Being in Sophie's world wouldn't be bad either
