As a music fan, I really love little mistakes in incredible albums. They’re humanizing, they show that the recording was made by people and it makes the highs feel so much higher.
As an artist, I loathe mistakes in my own work and I will spend a basically limitless amount of time fixing annoying performance quirks in software — I’m talking things that I can do but didn’t get quite right — so I can listen to it without distraction or regrets. I know that nobody will notice these except me and the type of listener who does catch them will either not mind or appreciate it the way I would. But when it’s my own work, it’s different. I’m sure it’s the same for filmmakers so I understand the impulse to fix it later.
