It might not be fair to say they don't give a shit. More often, I've found that productions simply hit a wall of time or money.

Just about anyone can write or edit a great story with enough time. But movies and shows are produced against a running clock, and they have obligations and limitations that go beyond the screenwriter's imagination or the editor's time. There are so many varied interests involved in a single production. Sometimes the issue is TOO many people giving a shit, and not being able to find a workable compromise in time.
