From my perspective, educational background, and experience working for over twenty years in television, this rant is spot-on and here's why:

Academic media qualifications (media studies degrees, masters, etc) mainly proved a hinderance rather an assett, when I went about recruiting staff. Why? Because what was really important was their experience in, say shooting, editing, and so forth. So the deciding factor would be showreels and the like, not their academic ramblings.

Unfortunately, some of those with degrees and masters in media studies subsequently employed in TV production felt the need to argue every little damn instruction, pontificating over mise en scene, and what the director might be trying to say about his repressed sexual feelings in a particular angle. I don't care. If you wanted to blither on about such things you should have become a film writer or academic. Just light the bloody shot and shut up.
