I was watching JE and a few more thoughts crossed my mind:

* I think JE is as much Rocehster's story as it is Jane's. I mean we know pretty much everything about his life...from his indulgent boyhood to his attitudes as a grown man.
And I was thinking ...that Bronte's purpose was to show that there ARE men like Rochester...who are frustrated with the way the current world around them works, sick of superficial appearances, play acting. These men want someone headstrong but also good as Jane. R also believes in the magic of the past (myths) unlike the others who are into balls and useless card games.
However, for a man like R to get someone like Jane, he as to ISOLATED. Thonfield is indeed is in a lonesome setting. So only if Jane goes to such a place, where R is not interrupted by any other people, he can get to know her ...and then fall in love with her. I guess this means that R could NOT have been as interested in Jane if she had been in a crowd (if you beg to differ, let me know your response)
And then also Bronte says that a union such as Jane and R's could only exitst in isolation because they have to go to Ferndean (and even Thornfield is burnt down). So does such a thing not exist in our life? Does this mean we'd have to live in isolation with someone in order to fall in love? How healthy would such a relationship be? Jane did get to know other people but her exposure to the world is not diverse. Also, R does know the people of the gentry and yet he chooses Jane. How would they carry on their lives? Woudl they not have to meet other people? What if R died early? Granted Jane has a fortune of her own...but how would she be happy without companioship? ..wait...there is Diana and Mary so I guess they'd keep her company though they would not mean to her as much as R did.
