Endurance is a Good Characteristic
Lets talk about the movie: It was well animated. The music was lovely. The scenes transfered at a good pace. At the end I was relieved to see a different view of the boy's face. Good stuff.
Lets talk about the message: Yes, everyday we are faced with drudgery and misery. Enduring these pains and making progress in our lives does strengthen our character and in the end, make us better people.
Lets talk about you: Killing people who annoy you shouldn't bring you happiness. Seeking relief from the pain is fine, but causing other people pain is shameful; it makes you a hypocrit. If you have urges to kill people, please seek help.
