That’s the worry—you don’t want to make something that doesn’t hold up at all. You want to make it kind of skeletal enough that people will understand it. You’re having a conversation with the screen when you’re watching a movie, don’t you? You talk to it, and you say, “What are you doing? Where are you going? How is that going to work?” And most times you totally understand the movie; even with the most tenuous of clues, you can piece it together and understand where it’s going. I think audiences can be incredibly sophisticated like that.
You really have to be careful with the clues you lay into the film—if they’re too heavy-handed, or you’ve pandered to a slightly stupider audience, then you’ve spoiled it for the people who are even slightly smart. That’s the worry. Also, a lot of people enjoy that teasing out of information and how that makes them think about it even harder. Otherwise, you might as well just have a banner up at the beginning of the movie that flat-out says what’s gonna happen and where it’s gonna go; then, everyone can relax because they know they’re not gonna have any problems understanding it.
