Another series which I was enthralled by when it was first broadcast, but rediscovery nearly 40 years later on DVD is a huge disappointment. A capable cast badly used by clumsy scriptwriting, ludicrous plots, and inept characterisations which meant I lost any interest in what happened or whether the "good guys" won. As mentioned by other reviews this series was the launchpad for Don Henderson's Bulman character, but at this stage he was just a nasty policeman with some half-baked eccentricities, more of an irritating cardboard cutout than the interesting role which later emerged. Some 70s/80s television is still well worth watching today (for the sake of argument - Sweeney, Sandbaggers, Travelling Man, Edge of Darkness), but this is not.
