The first episodes in series 1 are pretty graphically sexual but it gradually calms down. I find it addictive to watch and I love the concept that the individual skills and be used to 'step' into another personality in order to help - speak, fight, computer skills, detective skills etc. The joy, sorrow is felt by all. Each episode's plot builds and moves the series onward. Others have said they find it slow but I think that due to the complexity of the numerous interweaving strands that the plot has to ensure continuity and balance. I'm now half way through series 2.
