First off, glad you've recovered from the surgery, WG.
You see stories all around that aren't finished; it comes with Internet Fiction, so get used to it. I have been to many sites that have stories/fanfiction and there's not very many works that are ever finished; the author only posts one piece and that's it.
Although I never finished my first story, I did put a note in the reviews that I did not intend to continue. However, I fully intend to finish Julie. In fact, I think I'll submit Chapter 15 tonightStill debating whether I should leave it open at the end, for a possible sequel.
As for Hollywood endings... the final part of LOTR - Return to the King took ages!
