I believe that the comments of a solicitor (see earlier reviews) are completely true and the series is far from being realistic. But am I enjoying watching House (being a doctor of medicine myself) because it is realistic? Lol. Of course not, if I would judge it from realistic side, time, diagnostic, budget and ethical constrains we have in real life, House is an annoying and superficial series, turning medicine into a tragicomic theater - but I choose to relax and enjoy the show. Same applies to Silk.
Like House, the fun of Silk lies mostly in its dialogs and, to some extent, non verbal communication and narcissistic characters (in and out of the court). Note I agree Silk lacks building of the characters. We only learn about Martha. We are becoming almost obsessed with her, as the camera frequently stays on her face for loooong time. Thus, not much place left for others or to put in some more of a story. However, I need to disagree with the previous reviewer about Clive Reader character. The comment about him was: "When he is not being a jackass, he's as nice and loyal as a puppy." Emmm .... This sounds like a stereotype of a successful alpha man and I definitely know a few like him (unfortunately not that cute to be worth making use of it).
I am a bit puzzled how some characters (Kate Brockman? - I thought she was allowed to stay?) disappear completely out of series as new ones get introduced. We miss the old ones, too. Am very puzzled over John Bright character as well. We are allowed to glance at his stunning and gorgeous appearance in almost every chapter, never to touch under surface - I wonder about his work and why is he sitting in the office ... Acting is good, but many times slightly exaggerated (theater style) - an example would be Jake Milner character. Pushing it a bit too far (but cute anyway).
The series seems underrated to me at IMDb. I promise it wont insult your intellect if you understand the concerns I raised above and have no expectations of any realism. It will give you an interesting drama, tension and sublime interactions. I love it, even though it looses its way at times. I think it is very enjoyable, much more than any other series I have seen.
