I usually try to avoid dramatisations of novels I am particularly fond of, as they bring, in my experience, more annoyance than enjoyment or enlightenment. But I did watch the Colin Firth & Jennifer Ehle tv 'wet-shirt- version, & remember thinking it could be worse. In particular, I thought Ben Whitrow's Mr Bennet was perfect (even tho [& here comes the annoyance bit!] why did they rob him of the character's best line, "If any young men come for Mary or Kitty, send them in, for I am quite at leisure"?); & Alison Stedman, whom I generally find an OTT actress, was v right for Mrs B. & I have happy memories of Anna Chancellor's Miss Bingley & Lucy Robinson as her sister. (Anna C is JA's 8xgreat-niece, btw; did you know?)
I recall the Olivier/Garson version from when it was new & I was 8 or 9, but recall little; except that IIRC there actually was a bit of dialogue between them, "Why are you so proud?" "And why are you so prejudiced?". Talk about spelling it out!
But, even so, dramatisations into other media are one thing; reissuing the novels in updated rewritten form is another. I mean, why bother? Just write some new novels, why don't they? Let's have Moby Dick with radar & the Satyricon with Smirnoff vodka, why don't we?
