I find most movies to be predictable. "Hero's Journey" and all that. But I assume you mean less structural, and more like knowing exactly what they are going to say (or what jokes they'll use for a situation). I hate that.

But still, movies are (generally) business first, and art second. They don't even want to be "new"... just "fresh".

Nothing wrong with predictable, humans have been telling the same basic stories plot-wise for thousands of years. It's about how well you tell the story, not whether the story is original or not; originality is great, but it's too rare to be a requirement.

You'd be crazy to make a movie, and not try and pull on the well known well loved plot lines. It'd be like trying to make music with chords no one has ever heard; it'd be terrible. People want something familiar.
