Charlie Derry’s review published on Letterboxd :
At two and a half hours long I found it a little hard to get into, but it was definitely worth sticking around for. Casey Affleck performs brilliantly, so much so that it's hard not to feel sorry for him at the end of the film when nobody else will. The whole cast is great with strong performances throughout, and the cinematography is really impressive. The score and narration also work really well to give this character study a chilling edge, making it easy to see why so many people love it.
