So, there are a TON of deviations from the book. A ton. I think it's worth reading a recap if you're interested. I definitely liked the book a lot more. that being said, i thought the show, while a little slow at times (i'm looking at you traveling actors), was just beautifully written, acted, and engrossing. The scenes that were the most engrossing weren't because of the action, but because you were so drawn in by the actors and the music.
Does anyone have a better sad face/sad eyes than Mackenzie Davis?
My wife, who had not read the book loved the show. I thought the finale was weak, but still very good. I haven't seen many better acted shows this year (plug for Mr. Inbetween on Hulu if you want a really well acted show that also has a lot of action).
