I’ve just received, and have happily started watching, Doctor Who Series 9 on Blu-ray. I’m drafting a separate review post of that as I go along, but coming from a visually impaired person’s perspective, I’m very pleased to see they’re continuing with audio navigation and audio description on the discs. Sherlock gets the same treatment as well.
It’s not a feature I personally need to use, but I do have friends who use it. And it’s understandably frustrating that such audio assistance isn’t more widespread.
