And that's the only misgiving. There are scenes which are accurately and deliciously played, next to scenes that feel like ill-fitted improvisations. What went on? With no words or added explanatory bits to the boxed set, one can only guess that either commissioning, directing, editing or writing went awry or all of them at once in different ways. Actually, it's no bad thing not to tie every strand into a tight knot, because when a knot is tied (the villainous father explaining his motivation near the end) the script feels surprisingly underwritten. Despite this, there needs to be some credible possibilities ... and often there aren't. The world of compromise, suspicion and conspiracy is rich territory, but one that needs, I think, to be navigated in favor of reader/watcher. Despite thin characterizations,this is eminently watchable and full of 'blimey, what's going to happen next?'.
