I have just watched series 1 and 2 with my 15 year old daughter over the last week or so. I have to say I really think the 15 year minimum age rating is too low. A lot of sex scenes in there that are unsuitable ( I fast forwarded these bits while daughter covered eyes as requested by me at these points).
I have now watched series 3 up to the latest episode on my own. There is no way I would let her watch it, esp the bedroom scene recall. Seriously !! What do others think ?
