The one thing I appreciate most is the journey tigress has had. Full of rage, entitled, on the path to becoming tai lung. She fights what she would otherwise have become and loses.
Equally, shifu sees he’s destined to produce nothing but tai lung over and over again. Shifu realizes his mistake and completely starts over from scratch and together, he and tigress step off of the self destructive paths they were on. I just wish they’d shown more of it on screen, that would have been an excellent set of character moments. They’re not deep movies, so needing to read between the lines is odd.
