Steven Strait and Wes Chatham especially stepped up between series 1 and 2. I love that Chatham rereads The Churn, the novella about Amos’ youth in Baltimore to get into character for the show.
Frankie Adams, and yeah, she was great. I love that the producers refused to compromise on finding an actress of Polynesian descent and was built like a brick shithouse. With the exception of Ade in series 1, they’ve done a great job of casting within the ethnicities of the books’ characters. And even then, Ade’s only in one episode, and I can see some sense in changing her ethnicity in terms of Holden’s character
