My god, I feel pity for you "ending-guessers."
You truly seem to extract less enjoyment out of those 'surprise' kind of movies than other people.
You want to know a secret?
Most everyone else does NOT watch those movies with all their antennae up to try and glean every scrap of information they can for the sole purpose of mulling it over and trying to guess the ending before the ending is revealed.
Most people simply watch the film and enjoy it unfolding at the creator's intended pace. This way they experience the movie the way it's intended, not short-circuit it with meta-gaming (never trust the narrator, etc).
Why would people take pride in spoiling movies? I'd hide the fact that I suck the fun out of movies, myself...
Oh - and here's another sure-fire way to take some fun out of a movie :
Whenever you watch a romantic comedy, conclude early on that the couple will get together and fall in love.
Whenever you watch a heroic story, conclude early that the hero will win.
Don't bother watching the movie and going thru the ups and downs of the characters - just cut right to the chase and spoil the ending - that way, you're 'better' than everyone else. Props to your massive brains!
