"The yearly shoots typically ran between three to four days, after which Linklater and editor Sandra Adair would go to work. "Every year we’d spend a few weeks editing that episode, and then as we went on we would attach it to the episode from before," he said. It gave him the rare chance to reconsider creative decisions years after the fact. "In the end, it’s pretty unique to have ten years to think about a shot," he said, noting that transitions had been a particular area of focus. While the original plan had been for overt shifts as the film leapt from one year to the next, they ended up on the cutting room floor, resulting in one seamless ride throughout Mason’s life."

I thought it was fascinating to watch everyone age. But overall I didn't care for it as most others did. The story was not all that interesting to me. Maybe it seemed a little too life-like. In other words, it's a little boring. If what's above is true, acting 3 or 4 days a year does not seem like a big commitment, just a clever idea.
