I love this series but i find it hard to tell you why... perhaps it's because i am myself in advertising and i feel a certain connection to the deep and complex characters and the challenges they face in their working day. On one level it's easy to love because It's incredibly well filmed and brings the era to life in such a stylish way.
It's hard to describe exactly what happens in Mad Men, because a lot of the time when you reflect back on what you have just watched, it really is nothing at all. However, you are drawn in so deeply to the characters and the overall feel that you really don't care about the plot half of the time. Unlike other series that keep up a continued story line all the way through a series, each episode of Mad Men stands out as a piece on it's own, offering fantastic views and judgements on morality, family values, ethics and beliefs of the time and it can, at times, be punishing to watch. But above all i love it because it never apologieses for being so brash and unforgiving.
In summary, it makes for compulsive viewing and you'll find yourself comming back for more after every single episode, but only really you will know why. Poor a whiskey and let yourself be drawn in.
