The story was pretty simple and something you can find while listening to a true-crime podcast but it's a movie.

It's definitely not a waste of time but that's about it.

What I Liked
The commentary on how society treats deaf people rings true throughout the narrative, it also accents the police incompetency that will frustrate you

The killer is your typical unstable, grandiose, psychopath who was quite smart and thus could explain why he wasn't caught for most of the narrative

What I Found Meh
The cops like in most true crime/ horror films are a waste of taxpayers' money, none of them believed the victims because they were deaf and women and were really shitty at their jobs

All the women are victims with little to no agency for most of the story, aside from running away or crying, and that's kinda cliche, Despite there being numerous ways to fight off the killer.
While the men were the only ones to even hurt the killer (like the serial killer does more damage to himself than any of his victims)

Ratings Explained
The story is pretty solid, the acting top-notch, the music highlighted the moments but nothing really stood out.
It's a pretty straightforward narrative so rewatch value is not as high as the suspense is greatly reduced.
