I really enjoy this series, i truly do ! Why ? Not because i want in-depth scripts and complex personalities and such but genuine laid-back real-life drama. A TV series that you can get into from the first episode and by the end you know what's up. No need to watch the first 5 episodes before it all starts making sense. It's realistic and therefore it appeals to a lot of people even though most people haven't lived that sort of life or know celebrities for that matter. We know enough through the tabloids, TV, news, internet, etc etc. to know how some people can't carry the weight of success and they end up on the wrong side of history. We've seen many examples and of course we have also seen people that handle it pretty well too.
Whether they are athletes, actors or singers or whatever, they are all subjected to all sorts of seductions, schemes, paparazzi, and of course freeloading people around them. In that respect the series is very realistic. It is of course laced with predictable outcomes by that's all fine as they still make it all very enjoyable and easy to watch.
The actors they picked are very good for the roles they play so i don't see the negativism that some people have. Maybe they expected Grammy award plots, i don't know ...
It's just great entertainment, beautiful people & cars, good music, tight dresses and tailored suits and no psychic bloating.
My only point of criticism is that each episode is too short. It should be twice as long (50 instead of just 25 minutes).
