Couldn’t wait after UFC so I watched right away.
My take on the movie:
The “creatures” (or whatever they were) symbolize depression. Children symbolize hope. Birds symbolize happy moments and memories that should be protected and that helped at critical moments. Fugitives who did not use bandages symbolize people who appreciate death.
All the people who were in the house were going through difficult times and linked to depression. An unwanted pregnancy, the recent death of the wife or husband, the rejected nerd, the woman with a lack of self-love who is always looking to please others.
Everyone was at some critical moment, but trying to recover. However, the shadows, which symbolize depression, came to attack thoughts for suicide.
Finally, we are presented with the blind, and those would be those who learned to deal with depression and understood that despite the difficulties, the birds were always going to help.
