Was the purpose of this documentary PR (improving Taylor's image?)
I find it interesting that she switched from pop to 'poor people music' (indie folk) and even dressed like a rural person during COVID, which increased her popularity. Kind of a total re-brand at least until 'Midnights'.
Also her relationship with Joe was 6 years long, which is several orders of magnitude longer than the other ones. She had bad press for dating too many people prior to Miss Americana and by being with 1 person for a while this was good for her image. Now she is with someone that can helps her career much more than an introvert can.
