Since "Emma" and "Pride and Prejudice" are old news, I will just say that they should not be missed. "P. & P." is especially well done. It's marked by good taste and exquisite restraint, and the result is very hot stuff--by the end, you'll be ripping your own bodice.
Since the Keira Knightley version (which I loved, and not that it was her fault) got twitted for its excessive romanticism, I would just like to point out that, in this version, Colin Firth's hair is positively Byronic.
