A lifetime of longing for her father, coupled with that heartbreaking bit earlier in the movie where a supposedly senile Mama cries out for her father in her sleep.They have gotten better over the years, Remember Me is the best they have done. Everything they learned up to that point they put together in Coco. It has the most story impact, it is a godamn song being sang by a character, it could mean the end of one character's existence, it is about an elderly character remembering when she was a toddler, and has the entire family of the characters crying in front of them.
It's like they took all the most effective bits from their filmography and distilled them into one.
And this isn't the usual soppy romantic fare Disney movies go for, this is intensely relatable. Without being dark, we will all lose someone close to us within our lifetimes. I'd actually lost my Grandmother weeks before watching this film. It hit me where I lived, hard.
Ugly, ugly crying. Snot. Sobbing. Everywhere.
