When the director says he put a floating gun dream sequence 'just because' it's easy to assume the rest of it is the same, especially when the nature/mystery of the witch trap house is presented as the focus over anything you've described. It's been awhile since I've since it so I don't remember the side characters much. I'm imagining if Zone Of Interest presented the holocaust camp as its own mystery box while trying to say it's about suburban disinterest.
Also, try to make an argument without being a smuglord on here, please.
