13 Disney Scenes That Left You Forever Devastated

9. When Sulley Has To Say Goodbye To Boo

Devastation Rating: 7/10 You might not think of Monsters Inc as having many devastating parts - in fact, the monstery film might be classed as one of the more funny Disney movies - but think again. Big blue hairy monster Sulley having to return his surrogate human child back into the world where she belongs hits hard: a bit like losing your own pet might. It's sad because he loves her, even though he probably shouldn't. It's sad because she wants to stay. It's sad because she keeps calling him Kitty and no big blue hair monster ever suited such a name and its so cute and - oh god, just skip this part, it's too sad.
