This was a frustratingly stupid mess. This could have literally been solved within the first hour if it weren't for the absolutely idiotic behaviour of nearly everyone. The police were asinine and so were many of the core characters. The mother leaving out after the first encounter was face palming silly and a whole assortment of other ridiculous foolishness this movies gets up to that I'll spare you due to spoilers.
Perhaps the worst part of this movie was it's attempts at supposed messaging and social commentary. Primarily as it set up some of the silliest and most unbelievable scenarios to comment on the treatment of the disabled. A woman frantically running, screaming and being pursued by a man with blood all over him would set off literally everybody's red flags.
But oh no she can't speak so clearly she's deranged and we won't give her the time of day. THIS WOULD LITERALLY NEVER HAPPEN IN REAL LIFE.

The acting was fine, the music reasonably forgettable but I expected nothing less. This movie should have just been in the Door Lock, Blind school of inoffensive thriller that is just tightly written and done but some how they managed to make an absolute mess of it.
