I'm so glad there are so many others here who've watched the BBC version over and over.
I'm one of those people who get ultra-frustrated at moronic characters in fiction, even though it's fiction. I could not stand the BBC Mrs. Bennett, or Mr. Collins, but I understand that they're just ridiculous.
But I must say, to this day, I randomly spit out scenes from this version. Mary singing her song at the party. Lizzie singing that Henry Purcell song. "A friend in need is a friend in deed!" "Ooh, the soldiers!"
I only saw the 2005 movie in the theaters and did not like it.
The other monstrous BBC mini-series that's ultra frustrating but addictive is Bleak House. I'm starting Little Dorritt from the library this week. I absolutely loved the recent BBC version of Emma.
