I'll start by saying this was the first version I've ever seen, and after watching it, I decided to read the book (not the other way around).
When I first watched it, I really had no idea what the story was about so I wasn't on my guard, and some scenes really stroke me in an emotional level I didn't believe it when I first started watching it. Samantha Morton as Jane was very convincing, not a beauty, not ugly, then I found out that was how Brontë described her in the book. Jane was well mannered, sweet and tender, but with iron will and fire in her soul, it was a perfect combination of a heroin in the book who had to endure a lot of things during her life.
As for Mr. Rochester, well I'm a big CIaran Hinds so I may not be completely objective in reviewing his acting, but for me, he was PERFECT. Yes he yelled, he was too proud, sarcastic, but his raw passion and angst was right there you feel it, and specially in the parts where he seemed to touch heaven, and the other part where hell was right before him (those who read the book or watched the movie will know what parts those are).
The chemistry between Morton and Hinds is amazing, when they are talking under the tree, I really began to cry and felt overwhelmed by the intense emotion flooding my screen, and then in the same tree after the "event", I cried some more because I could feel the despair from Rochester and Jane's sorrow but determination. And finally, in the end, I cried more and more with the strong performance from the two of them.
I read the book afterwards, and yes many scenes are left out (gipsy, Jane's aunt dying, Jane's dreams, the tale of Bertha Mason, Jane's new found fortune, etc...) but considering they had only 1 hour 40 minutes to consolidate an 800 pages book, I believed they did a pretty good job.
I read some comments about people who disliked Hinds performance as Rochester, saying he screams too much, well personally I didn't think he "screamed", he raised his voice and Rochester does that a lot in the book. I watched another version with Michael Fassbender, and it lacked the passion this Rochester has, it actually made me yawn.
I highly recommend this version, the casting is great, overall the movie is very true to the book, and the strong performances given by Morton as Jane, and Hinds as Rochester, is really something not to be missed. If you imagined Mr. Rochester as a handsome, well mannered, with integrity, soft spoken and tender man (in other words, a Jane Austen hero, I can't imagine why somebody would imagine him like that), you will hate Hind's Rochester, but if you imagined as a non-attractive man in a conventional way, sarcastic, snappish, moody, witty, intense, rough, tough, passionate, angry but tender when he must and overall, a tortured soul who finds redemption through pure love, you will not be disappointed with him.
