So the idea is in order to have this perfect society where everyone is safe and fed and has a home, there can be no emotions, not just unhappy ones but happy ones too (there's a discussion between two of the characters later on in the movie so again, if you haven't seen it, check it out; I don't want to spoil too much of it).
Dealing with Difficult Emotions
Emotions good and bad are eliminated.
And yet having emotions is what makes us human.
So it's kind of interesting how we as humans have a sort of love/hate relationship with our emotions and how some see suppressing those emotions as the ultimate way to advance as a species. Perhaps we fear the primal side of those emotions. However, one skill we learn as those who are especially emotional is to accept our emotions, both the positive and the negative. The emotions in and of themselves are not the bad thing. It's our response to those emotions that can be destructive.
Thoughts? I'd love to read them!
