Not a movie, but when I played FFX on release I enjoyed my time in Spira all around.
When I got it years later on Steam and played it again, only then I noticed how drab and plagued by death the world of Spira is underneath all the cope against constant extermination via color and desperate-cheerful mentality.
Just as OP said, really showed me how my mind matured over the years and experience.
And fuck yeah when I 100% FFX2 and all came full circle into a happy ending.
