Finally watched this over the weekend.
I really liked it, I had heard about this movie and I was putting off watching it for some reason. I wasn't mentally prepared to watch as someone losses their hearing, but I'm definitely glad I watched it.
Riz Ahmed did a great job as the lead character. Great sound design and editing, which this movie won Oscars for both those categories.
It's streaming on Amazon Prime, so if you have Prime you have no reason to not watch this.
