Genghis Cohn Reviews
I saw this as a BBC "screen 2" production in the early 1990s. it was memorable. Just rewatched it from the from the youtube VHS uploads, and it still hit a raw nerve.
No doubt it's an imperfect adaptation of the source, but the dynamics between Robert Lindsay, Anthony Sher, and Diane Rigg cut through.
You'll be offended if you want to be, challenged if you are open to it , or laugh if you can suppress the pain.
