It's interesting that so many books now are published as the first in a series. It never occurred to me. Although 'The Giver' does have an ambiguous ending. I've heard about that from readers over the years.
....there is an ending [to Infinite Jest] as far as I'm concerned. Certain kind of parallel lines are supposed to start converging in such a way that an "end" can be projected by the reader somewhere beyond the right frame. If no such convergence or projection occured to you, then the book's failed for you.
You see, unlike in the movies, there is no THE END sign flashing at the end of books. When I've read a book, I don't feel like I've finished anything. So I start a new one.
The challenge is always to find the good place to end the book. The rule I follow with myself is that every book should end where the next book would logically begin. I know that some readers wish that literally all of the threads would be neatly tied off and snipped, but life just doesn't work that way.
We got offers to make sequels to both 'Shaun of the Dead' and 'Hot Fuzz,' and they never really interested us because we like having these endings where it seems very final but could hint at some kind of future adventure that you'll never see.
I don't see novels ending with any real sense of closure.
At the end of the day, the end of the movie is sort of ambiguous - it's whatever you want it to be.
The idea of viewers getting invested in a series is that you're getting invested in the reality of these characters' lives that, in fact, don't have an ending.
I don't like when you necessarily know that this is the end of the movie. I like when a movie ends abruptly. You go through this, and some of the scenes are uncomfortable, and some are funny - and then suddenly it's over.
