Editing isn’t the most important part of the movie.
IT IS THE MOVE!
You can also read acting books to contribute to how an editor creates pace and rhythm in the edit. We editors get a Wide Shot, a Medium Shot, and a Close Up shot of the same few lines. By understanding what subtext is and acting beats, editors can manipulate the performance. Cutting to the close up on the dramatic beat in the scene. Or cutting to the wide shot for a punch line, followed by CU of reactions.
