I love Chainsaw Man so much, but watching this movie reminds me of the absolute sadness I felt and couldn't shake for weeks when I read the manga a couple of years ago. I won't spoil anything, but it absolutely nailed the tragedy and really pushed it to the limit of what it could be.
The Reze arc was my favourite arc in the manga, and it was perfect to adapt into a film. Since reading a few years ago about 10 chapters into part 2, I've not gone back to the manga just because I'm reminded how fucking sad it made me. And watching this beautiful film and seeing all the characters again, I'm like shit imma have to go through that all over again with the next couple seasons of the anime
All that to say, I absolutely love sad shit. I love when characters I love get hurt and go through hard situations, but nothing has ever left me feeling as empty as reading the chainsaw man manga. Do with that what you will
