I think those films were going to do well whatever was in the trailers.
For myself, surprise is rarely what matters to me.
I don’t go out of my way to read spoilers, and I’ll actively avoid them if they’re the kind of movie that’s built around them. I didn’t want to know who got killed in ‘Infinity War’ or who comes back in ‘Endgame’ for example.
But most films don’t rely on twists or surprises.
