The Importance of Exposition in a Movie

This movie is one answer after another that we didn't have a question to. The thing in the beginning feels like a light thing like added it after they did a test. I think some people were confused what was reality and wasn't but they looked so cartoonish. They put on the glasses they're in the oasis. It's fine. If I had to bet I bet that whole beginning that prologue came late in the game. How about that?I just had that feeling though. I guess they have a lot of material that they probably had to shoot for it.
