I think if you’re watching or reading something you KNOW has a twist coming, it’s not actually an “unexpected twist.”
Reminds me of when The Sixth Sense came out and my sister said I should go and see it, it has a great twist at the end. So I watched the first five minutes knowing there was going to be a big twist at the end and wondering what it could be… bloody worked the whole thing out. Before the opening credits had even finished from what I remember.
