I was also surprised the murder was depicted but then again who could be bothered to sue? I get the feeling the Lucan family want to forget all about the murder. It was graphically depicted, which I was also surprised about, in a very matter-of-fact, stark way, which made it all the more chilling.
I wonder what will happen in the next part - I hope they don't focus on Aspinall and the rest of the gambling set to the point that the Lucan and Sandra Rivett families are neglected, story-wise.
Small gripe but great actress as Catherine McCormack is, her lack of resemblence to Lady Lucan was a little distracting for me.
I'd recommend anyone watching it on catch up.
