Kolishav myth that individual shots, which may be low on meaning or emotion by themselves, can become highly charged with meaning by the power of the surrounding editing.

It raises really interesting questions like, what are the properties of the maximaly kolishav ambiguous face? You know, what kind of skills would you want an actor to have to be able to have these?
