Anti-mental illness. Support this and you're basically scum. Perhaps not intentional, but it is what it is. The villains and pariahs are like you and I; and in a film where nobody could even handle the material (source nor adaptation) properly, or with an ounce of understanding and clarity of sight. Awful, and you're awful for liking it. A degenerate's playground is what Bird Box is.
May Eden exempt those who are unfortunate enough to deviate.
