For months now I've had family and friends tell me how much they enjoyed Inside Out and telling me that I should see it. I finally got the opportunity to in a hotel room at three in the morning. Everyone else who was watching drifted off to sleep but I had to see how it ended, and basically it ended with me trying not to cry loud enough to wake up everyone else in the room.
The movie gets that the inside of a person's head is messy. None of the systems communicate well, one emotion tries to dominate and fails, memories fade and are lost, things that you cared about go missing. The human mind is a confusing place that wants to think of itself as clean and simple and ordered but can't pull it off.
Of course Sadness was my favorite character. I get sadness. I get how important it is to be sad sometimes but I like the message that balance is important. You can't be happy all the time, obviously, but being sad (or disgusted, angry, or afraid) all the time is no better. And I like that the movie's main message is to ask for help. If you're losing your emotions, if you don't feel the things you used to, if you're scared and angry and can't feel joy there is a problem and it's completely acceptable to tell other people what you're feeling.
Good job Disney and Pixar, you've made another brilliant movie.
