Here's my opinion which differs from your opinion:
If you ask engineers or mathematicians, they'll tell you that what they do is also an art. I disagree that art is all just instinct.
Film school isn't the death of your career. I think this people actually did go to film school: George Lucas, Martin Scorsese, David Lynch.
How do you know if a movie is really great (e.g. Citizen Kane) if you don't study its intricacies? I think analysis is important.
Hey @boxofbits, thanks for letting me know your point of view. Its always educational for me if there's an opposite opinion. And I do respect your opinion :)
