Educators paint a pretty picture indeed.
Student training, however respected the institution of learning, is not nearly taken as seriously as direct exposure from an industry standpoint. Very good people frankly have seen an awful lot of errors of judgement. Making a film in particular has been described as dozens of people standing around 12 hours a day asking questions. No matter what you do, where you are in the chain of command, the staggering number of variables means that workers operate in a kind of damage-control mode, asking the most pertinent questions, all day, every day, to construct the best course of action to get the job done. This is why entertainment industries are so structured and why 'rising through the ranks' more often than not produces the best people.
