Plot twists are always good for stories. Unfortunately, if you introduce them too abruptly, they feel contrived.
Case in point: as I noted in a recent Bubblews post,* there is a twist in the 2000 Clint Eastwood flick Space Cowboys that was very jarring. In it, a photographer with improbably easy access to NASA photographs Clint and his team of aging but fit Air Force vets out for a morning physical fitness run while training to take part in a special mission to a Soviet satellite about to fall out of orbit.
The following was not explained about this character:
-Why he was at NASA
-How he got into NASA
-Where he got his tip about Clint and his team
Jarring plot twists like this also leave them feeling contrived. Granted, contrivance is a part of making believe about something when writing a novel or making a movie, but if you push suspension of disbelief too far, too fast, you lose your audience, in my opinion.
Whenever you introduce a twist in your story’s plot, be as smooth about it as you possibly can. That way you will not lose your audience, but continue to keep them hooked.
