My example of a good use of space in a film is this scene from Avengers: Age of Ultron

This use of space here is to show dominance and power in the character of Ultron.

This is done by having this shot seen below come in after Ultron has cut off the arm of the other character, Ulysses Klaw

This scene not only portrays ultron as a dominant character but also gives the audience a sense of his scale and size which again adds to this scenes portrayal of ultron as a large, scary and dominant character
