An example I can think of that violates audience expectations is the book The Westing Game. I remember reading that book in middle school and being very surprised at the ending. I think the attempt of changing the audience’s expectations was very successful. The author did an excellent job of making the audience think the killer was someone throughout the whole story, but then they switched it up at the last minute. If done successfully, playing with genres can pull in the audience and be entertaining.
Oh my goodness! I am so obsessed with The Westing Game! Your explanation of this definitely articulates how I'm feeling about the plot-twist in the book and the movie.
I forgot about that book! This is a great example and I completely agree that the switch in the last bit of the book was done well.
Wow, I remember reading that in middle school and being totally shocked by the end. I agree that it was a successful attempt as I was entirely pulled in from the surprise.
