My favorite so far is Downton Abbey. Its set on the eve of World War I. Its worth watching for the interiors alone. Bonus - season 2 will be available soon.
Another goodie was North & South. Somewhat similar story to P & P, but enjoyable.
I really enjoyed Daniel Deronda - a George Eliot book I haven't read. The heroine reminded me of Middlemarch - not exactly the most sympathetic. Will have to read it once I am done with Middlemarch.
The Way We Live Now is an Anthony Trollope book. The show was pretty over the top - dramatic music and the like - and was my least favorite.
What's up next?
Bleak House (A Dickens novel I've never heard of...)
