The plot is doing something

School habit demands of a work of art a main idea that can be retold in one sentence. A good work does not always deliver a thesis: it can create an experience, explore form or make you see the world differently.

It can create an experience, explore a character, show a world, play with form or simply give pleasure. A spectacle does not become bad merely because you cannot write down a one-line moral afterwards.

It is more useful to ask:

What does the work do with this particular form?

A book can convey inner speech, extended reflection and a complex structure of time. Film works with the frame, editing, movement, sound and the face. Theatre creates live presence, shared space and a performance that never repeats. A game adds the participant’s choice and action. Animation handles physics and the image more freely.

An adaptation does not have to copy a book literally. Moving into another material demands a new solution. A good adaptation keeps what is essential and changes the means of expression.

A recorded stage production really does lose part of its theatricality, but it can gain close-ups and editing. A photograph of a building will not replace being there, but it can show a detail the visitor missed.

A work becomes weak not because of the genre chosen, but when it breaks its own logic for no reason, replaces development with coincidence, or demands from the viewer an emotional reaction it has not prepared.

Even then it can be fun. Not every film is required to be a philosophical treatise. Sometimes a dinosaur simply has to step out from behind a tree in style.

What the form is doing is easy to check by transfer. A novel half of which is the hero’s doubts loses, in adaptation, exactly what it was written for: on screen doubt looks like a man standing silently at a window for a long time. So the screenwriter invents a conversation that was not in the book — not out of disrespect, but because film can show a thought only through somebody’s face and somebody’s words. Readers call this desecration, though a literal transfer would give three hours of silence.

The reverse case is rarer and looks the same. Retelling a film in words means throwing out the editing, the pace and the face, that is, almost everything, and getting a plot that on paper seems banal. Retelling is a poor test of quality in general: the only thing that survives it is work made entirely of plot.
