This is the answer. For those of us who were born before 1990ish, it's easy to think perfection is the goal. Perfection has long been the sign of the skilled hand. However, in today's world, perfection is the sign of computers and automation. Perfection is everywhere. Perfection is cheap and it's boring. It's the hallmark of the unskilled laborer, not the skilled master. To people who grew up after the digital revolution, there is a decided lack of human touch on everyday existence.
When photography first came out, it was accused of killing painting. It made no sense to pay a highly skilled painter to paint your portrait when a photographer could do it more quickly, cheaply, and accurately. But painting didn't die. It evolved beyond realism. Abstraction took over. Expressionism reigned. Surrealism flourished. Photography didn't kill painting; it freed it from the bonds of everyday experience and placed it on an ethereal plane, free to find it's own meaning of existence.
And that's what digital has done to film. Making a perfect photograph with film still takes a lot of skill, but it will never look as good, be as cheap, or be as quick as a digital photo (remember we're still in the infancy of digital sensor technology). As such, the whole reason for shooting film for most people who grew up after the digital revolution, is to "show the artist's hand", as the saying goes. The whole point of it is to show off the flaws. It's to reinforce the idea that it was made by a human, for humans, and in celebration of the human condition (flaws and all). Perfection is no longer a goal, or even a desirable trait. Film is no longer tied down by the expectation reality. The flawed nature of expired film mirrors the human experience. The flaws of expired film are a metaphor for ourselves. It's unrealized potential at it's finest.
So the real question is, why shoot film over digital if what you want is reliable and repeatable results?
