White Heat...

... seemed to finish with a whimper.  Was anyone other than Ali still watching?  Not in the league of 'Our Friends...' and definitely not event television.  Among the many possible reasons, two stand out: the casting of actors who bore very little resemblance to their younger selves and the fact that most of the drama seemed to arise from personal circumstances rather than the a-changin' times.  Ironically, the rather clumsy attempts to ground each episode in current events, music etc. took attention away from the development of the characters and their friendships, making it hard to care about them, or believe in their supposedly deep and lasting ties.
