....the 1998 A&E miniseries Vanity Fair.
Oooooh. Excellent, excellent, excellent. If you have a spare FIVE HOURS to kill, it is definitely worth your time!
Very true to the book, as I remember it. No sugarcoating of how devious and calculating Becky Sharp is. The subtitle of the book is something like: "A story without a hero." While there are a couple of noble secondary characters, most of the people are shown for the cads and bounders that they are.
One of the complaints I read about the new movie version of it (starring Reese Witherspoon) is that the directors felt compelled to make Becky sympathetic--giving her reasons in her background for how she acted. And making her more of a mother to her son that she actually is in the book. Too bad.
Political correctness did not win out in this miniseries. If period drama is your idea of a fine time, then put this one on your list.
