Annoyingly ill-defined “monsters”
One of the worst things about this film was how poorly defined the monsters and their abilities were.
* They are invisible, but they still cast a shadow and looking at them makes you suicidal.
* Wait, looking at them doesn’t just make you suicidal... it can also make you a clever psychopath (who can create a cover story and form an armed gang) who forces survivors to look at the monsters.
* The monsters need people to act as their proxies and make survivors look at them, presumably because the monsters are intangible. And yet they still have weight (one shakes a large car and sets off its sensors), make noise (wind howling), can imitate voices (in the woods) and manipulate gravity (the way the leaves and dirt lift)?
