wp had a long discussion some years ago about whether or not to include spoilers in film articles and they decided that their mission of sharing info would predominate. So the spoilers stayed in their articles.
So the lesson is: don't read about movies on wp until after you've watched them.
What really pisses me off is streaming sites that put major spoilers in the promo blurbs.
Or even spoilers in the movie trailers. That sucks.
