I really like the amateurish feel, because it makes Jane seem like a real person and I admire her bravery. (Have I said this before?) I didn't want a modern Jane Eyre vlog, I was convinced it wouldn't work, and am rather delighted to be proven wrong.

You're definitely right when you say a lot of this will come down to Jane and Rochester's relationship, and whether the balance and the equality are there. It is a relationship dynamic which could be very easy to get wrong.

I suspect that depends on how much we see of Rochester on camera, or how much Jane talks about him. Jane doesn't seem to be very comfortable talking about others - not if they inspire strong emotions in her. I doubt she'd criticise her employer to the internet, but to his face, yes.
So I'm hoping we get Jane refusing to be intimidated - and Rochester's delight that she isn't (as opposed to Rochester just being grumpy and overbearing).
