I have to say it is my favourite TV show on at the moment. I particularly like the voting bits where they read the same scripts, but have slightly different situations and have to decide whether it is acceptable or not. Tonight it was whether it would be racist to want your child to marry within 'your kind' and they did Jewish, White and Asian.
The only thing I would say is that sometimes the results are a bit superficial. For example, when they did the restaurant last week (the racist waiter), no-one in the Manchester restaurant spoke out. Was it because of location, or was it because the demographic seemed younger? It often seemed as though older people spoke out more than younger people. I don't think it is particularly scientific in that sense, but as a bit of light entertainment, it's been fascinating.
