It’s no secret that movie trailers nowadays are prone to giving away too much of the movie* (a prime example is the remake of Speak No Evil).
Recently, I have made a personal choice to see a trailer only once or so (and very rarely do I seek out a second trailer of a film). This is one of the key reasons as to why I went into Blink Twice without knowing anything about it other than seeing the poster and possibly (I can’t remember) seeing the trailer once a few months ago.
Nothing else to say
