Gripping from the first snippet shown on Netflix. Without even recognizing Mel Gibson, who is submerged in his character, I was caught up in the story. Production values excellent down to the smallest detail of this gaslight era- the copperplate handwriting, the flashbacks to the American Civil War, the severe upholstered look of the women's clothes, all of it. Not many actors could carry off a part like Dr Minor but Sean Penn manages the dignity of the absolutely mad. Of course, I love to read, I love words, I love escapist reading, so this piece really speaks to me. I'm sending it to all my compulsive reader relatives.
