While watching Austen is a pleasant enough occupation - those with access to French/German channel Arte can follow the excellent BBC series 'Pride and Prejudice' forthcoming two Thursdays - all her 7 novels with regard to the mere plots, boil down to banal love stories.
Austen's textual body, however, abounds in scathing social criticism with a feminist backbone, all in witty phrasing and biting irony. It just seems a pity to reduce her to who-marries-who-schemes.
As to Joe Wright's 2005 adaptation, it sums up the whole novel in barely 2 hours, which induces significant cuts in the narrative. The pictures are pretty, though.
