One of my current favorite TV shows is Downton Abbey. It’s full of drama, awesome costumes, and plenty of snark. Brilliant! Unlike so many Masterpiece shows, it’s not based on a classic novel. But Book Riot has taken care of that with their literary casting.
My favorites: The Earl of Grantham as Henry Dashwood and The Dowager Countess as Lady Catherine de Bourgh. But I disagree with Lady Edith as Fanny Price (Fanny is not so ineptly evil!) and Lady Sybil as Marianne Dashwood (Sybil seems like a combination of Marianne and Eleanor, actually).
