Alone

How quickly the story moves scene to scene.

Filmmaking quality — direction, writing and recognition.

The sustained pressure it keeps you under.

How bleak the tone and subject matter run.

How much it is designed to move you.

How often it is genuinely funny, by design.

Physical momentum — chases, combat, set pieces.

How much of the story is withheld and unravelled.

How much attention the structure and ideas demand.

Scale, imagination and the sense of the extraordinary.

How central love and intimacy are to the story.

How much it is built to unsettle or frighten.
