Yes, we actually stayed up until 1:15 to watch it (normally asleep by then). I thought it was really well acted, particularly Simon Cotton (Ronnie). Yes it was violent but I suppose that's what you would expect.
No I didn't watch it.
I think some of these programmes give publicity to and 'glorify' criminal and thugs and add to their air of mystique particularly with regard to a certain set of people with psychopathic tendencies.
