People just don't get it.
A spoiler is not the story of the movie (or book, or whatever).
A spoiler is not how the story ends.
A spoiler is not a particular important piece of information regarding the story.
A spoiler is EVERYTHING THAT MAY SPOIL THE MOVIE!!!
And includes stupid sentences like "Oh, but the end is really surprising!"
That does spoil the movie, you know? Because one keeps thinking on what odd twist can the movie take by the end and half the fun is spoiled while thinking about it.
And telling me the blood in a given movie is of a particular color doesn't help!!!
Good thing no one reads (spoiler alert) the crap I write anyway...
(though I didn't mention any blood...there was Christina Applegate though...but I didn't mention her specifically...just the bad acting in general...I'll stop now)
