So I finally caught this, ever since it was a little over-hyped at the time of its release I assume?

I came in expecting a film about a toxic mother-and-son relationship; similar to Xavier Dolan's "Mommy," but the opposite. However, it turns out it's not the mom that's toxic. The entire freaking thing is toxic.

There's that, and the fact that this film is also very nerve-racking. By the end of the day, I'm only here for Nagasawa Masami's brilliant performance as the one who primarily carries this work of art moving forward.
