I am SO much better at pointing out what I don't like than what I do, so bear with me. If I don't mention something, it's likely because I found it just fine. :D
The music was too loud - it drowned out the dialog at times. And since the dialog IS the story, that's unfortunate.
Many times, even without the music, it was difficult to understand what was said. I have gotten used to that in TV shows, but it's very distressing to find it in movies, now, too.
Let's not get me started on the costumes, k? Although I did find it amusing to see the older women in older styles since that WAS realistic. Keira's posture sucks, however. And the clothing they put her in was NOT flattering to her (not so lush) shape. Unfortunate, again.
The acting was great, however. Only once or twice did secondary characters make me go "um....".
But, but, but they left out the opening line! The oh-so-snarky one about it being common knowledge that a man of good fortune MUST be in want of a wife. I mean, that set the tone for the whole book and they left it out! Nothing else I considered 'necessary' was left out, however, so I suppose I forgive them. But, still..
