Almost too overwhelming.

Rating: 10/10 (22 May 2019)

Other reviewers have pretty much said all that needs to be said about the movie so I'll offer my experience.
I watched this with English subtitles so I don't feel like I got the 10 out of 10 experience.
I'm also not sure what rating to give it. It clearly deserves a 10 out of 10, but at the same time it's such an assault on your senses that it's almost un-watchable. And it's a long movie. I had to watch it in two parts over two evenings. I couldn't handle the whole movie in one sitting. I felt like Alex in A Clockwork Orange. Throughout the entire movie I never stopped thinking, "What the F#ck?" because everything the Nazis did was What The F#ck. Schindler's List was an assault on your heart. Come and See is an assault on your mind. The protagonist lives from one WTF moment to the next and you wonder how anyone wouldn't lose their mind. I kept thinking, "What the f#ck am I watching? What the f#ck is going on?", which was clearly the protagonist's state of mind.
The movie's message to me: The Nazis turned Belarus into an insane asylum. A madhouse.
You have to watch this movie.
