Have you heard of TV tropes? It’s a wiki of … well, tropes in story telling (warning: for some people following a single link to https://tvtropes.org/ means they find themselves half a day later with 32 tabs open and having read up on all kind of story tropes while having forgotten what time is).

On the one hand it will help you recognize the tropes and figure out how many of them are used in all story telling (yes, even the good ones), but on the other hand it can help appreciate that it’s not the tropes or the broad strokes that make up a story, but how well it’s told.

There’s a reason there are so many movies/stories/plays that are just re-tellings of some Shakespear play or another: it doesn’t matter that the outcome is known from the start. The journey and how well it’s told is what’s important.

So basically: “Oh yeah, that guy’s gonna betray me. I wonder how and why exactly!”
