Maybe I'm missing something, but the only point of this film seems to be to emphasise that the victims of mass shootings are normal people leading mundane lives with no clue that they will be involved in a mass shooting before it happens. That seems so obvious it is not a point that needs making, which makes this a film that didn't need making.
Most of the characters are nameless and no flesh is put on the character bones. No emotion is evoked. Even as an unsensational snapshot of normal daily life it seems abnormally devoid of life. Mundanity is emphasised to the degree that you feel these are not normal people - they don't seem representative - they barely talk, they are all flat in affect and extreme in their inactivity.
Once all the things this could have done have been missed or avoided it can only be a Who's-Gonna-Do-It. I don't get it.
