To use an old cliché of therapy-speak, we spend too much of our lives seeking "closure"….What we need more of, instead, is what the psychologist Paul Pearsall called "openture".

If you choose a life of awe, you will surrender the solace of certitude. You will live with more 'open-ture' than closure and, unless you can learn to find a strange, exciting comfort in being presented with and grappling with the tremendous mysteries life offers, you will seldom feel calm or at ease for very long.

Still, the writer and director [Joss Whedon] jokingly cautions that Serenity is not the start of a trilogy. "If I never got to shoot anything of Serenity again, I would still feel that I had told my story and I had given the actors what they needed and the fans what they needed and myself what I needed. There is closure here. But having killed Buffy twice, I'm also a great proponent of 'openture.'"
The first citation describes "openture" as an "awkward neologism" (what I call an awkword), and that it is. It's also awkward etymologically, since closure is essentially a blend of close and the suffix -ure (used to denote an action or process), so by analogy openture must be opent + -ure. Opent? Let the scratching of the heads begin.
