Quick question...

i dont know

Not trying to sound too clinical, but there are some personality types that genuinely don't like surprises, even if it's just in the plot of a movie. A surprise unsettles them, makes them feel that things are uncontrolled or chaotic, and that makes them angry or agitated (the degree of the anger depends on other aspects of their personality. Some people can get *really* upset by it.) If a movie takes a turn that they don't see the logic for, then they're going to see it as stupid, unintelligent, or annoying.

It's just another way of processing data input. We all have our different strengths and weaknesses in how we react.


You might very well think that. I couldn't possibly comment.

This isn't a direct answer to the question but something that does annoy viewers/readers is when a story is badly told.
Surprises are good but it should be possible for the intelligent reader/viewer to take on board the new information and say to themself 'ok that makes sense, I can see how they got there'.
If not it strikes one as lazy writing of the kind where "with one mighty plot device jack was free".
In something like the 6th sense (say) one can review the film and see from the start that the writer was consistent but chose not to explicitly reveal the truth.

SO i guess my answer is that i don't think it is being surprised that causes the problem - people generally like that in a movie. What they don't like is to feel cheated by poor storytelling.

In the context of Seraphim Falls, it's not so much the final ending that causes consternation but the writer's choice of introducing a supernatural element along the way. The story was zipping along quite well up to that point and I believe the charcaters choices at the end would have worked just as well without the explicit introduction of Charon and Louise C Fair.
