It wasn't terrible, but it definitely pales incomparison to the BBC version. The actor playing Darcy was fine, but he was no Colin Firth!
Kiera Knightly did a pretty good job with Lizzie, but the story is very condensed, and it has a "Hollywood" ending that is completely out of context and could vex Austin purists.
Still, not a bad way to pass a couple of hours. Go in with the lowest expectations possible and be pleasantly surprised!
