Oh dear. Very infactual and the chav accents of the sisters (and Bramwell) made me laugh aloud.
I live in the area and they did a great Jo making main street look authentic, and the parsonage set was brilliantly made, but they shouldn't walk straight out of the parsonage onto the moors. The moors are quite a way up Haworth.
Nice to see the village on TV, but a big let down.
I watched it with my family, and we also found it difficult to understand some of the dialogue. However, I think it's a common issue with a lot of modern TV, where the makers strive for authenticity in the form of more naturalistic - and therefore, in their eyes, more realistic - dialogue.
It could be the sound editing/recording wasn't up to scratch, or it's an issue with the acting, and how the actors in question were directed. It's a shame, as I don't think the performances were poor, they were just let down by the dialogue. I've also heard criticism that some of the dialogue sounded too modern, a view I share.
I also expected more to be made of the setting, especially as it was such a major part of the sisters' upbringing and their writing. It also felt as if their writing was a secondary plot line compared to the struggles of their family life, particularly with Branwell. We did get to see their legacy in the final scene set in modern times, which was designed to show their influence. However, the plot never really explored the impact that Charlotte, Emily and Anne were having to any great depth, so the final scene felt out of context.
Overall, considering the impact the Bronte sisters had on English literature, it's a missed opportunity.
