An absolutely great video about the Doki Doki Movie and Pokemon The First movie's handling of death and mortality. (The video doesnt require watching either movie but spoilers galore)

I saw the Doki Doki Movie but this analysis is great. Doki Doki is one of the few movies of Precure I actually sat down and watched in its entirety. I didnt love it but now I have a lot of respect for it. Love can live after death. It can be passed down.
