Some editors are chosen for their creative input. Sometimes it is the editor that convices a director, but it's often a collaboration. Editors are part of the creative team of a production compared to just a grunt level worker. The director, DP, and editor can all collaborate so that the image is conevying the desired feel to match the story and vision. Or so the theory goes.
Absolutely. But within epsilon of zero editors on a real production are just having it dumped in their lap without direction. It's a collaborative thing at best and the post to which I replied is the same sort of sneer-at-the-grunts attitude that makes people lecture the Starbucks worker for company policy.
