I thought it was written and acted in such a way as to be acceptable for children to watch with their parents. That's what the review I read said, anyway.
As I've already said...this is NOT another version of the original RLS story...it's altogether different. Anybody expecting the original story will be moaning on here Sunday night (Remember The Musketeers re-imagining...nothing like the original....and Sherlock, too!)
Must admit I was surprised to see it was on at 6.30pm after watching the preview, I felt sure it would be on at 9pm. It's not a problem for me personally as I don't have little children in the house, but if I did, I don't think it would be something I would watch with youngsters around.
It has been adapted by Charlie Higson and comparisons have been made to Doctor Who so it seems very much to be aimed for the teenage market. As soon as I saw the transmission time I lost interest.
