Currently watching The Mysterious Benedict Society on Disney+ with DS12. No one has been murdered, I can hear what is being said and it is beautiful, all pastels and argyle print instead of the usual dark and brooding scenes where you have no clue what is happening.
Also, just started Sweet Tooth on Netflix, again you can hear what is being said and see what is happening. It is cert 12, but at times my son was "concerned" about what was going to happen next and shouted at the screen.
