First keyword for "Everything, Everything" (2017) is a plot spoiler

Col: I'm not sure what it means for a keyword to be a spoiler only for those who have actually seen the movie. Surely a movie can't be spoiled for someone who has already seen it. That would be like the episode of "The Larry Sanders Show" in which Hank (Jeffrey Tambor) has to ask Gene Siskel what the plot twist of The Crying Game was, because Hank had watched the film but somehow failed to see the revelation of the secret.

It means if you have seen the film, the keyword looks like a blatant spoiler because, having seen it, you appreciate the context.  If you have not seen the movie then it's just one of a group of keywords whose importance cannot be judged without seeing the movie :-)  

Another example: there are 371 plot keywords for Titanic (1997) and one of them is lovers-reunited-after-death which seems harmless enough but it could be read as a huge spoiler after viewing the movie. 

It happens even more with trailers. Trailer editors frequently include sequences from key spoiler scenes in the movie, yet out of context, they look totally harmless. Only when you re-watch the trailer after seeing the movie do you realize it has spoilers (the identity of the villain is revealed in this trailer for The Da Vinci Code (2006) -> http://www.imdb.com/videoplayer/vi3438280985 yet you would not realise without first seeing the movie so it's a non-spoiler spoiler :-).  I only watch the trailer after seeing the movie so I am particularly susceptible to noticing this.
