I am sure that the promotion for this story stated that this would be the last one. I recall quite clearly sitting down to watch the last episode knowing that it was the series finale. As far as I am concerned the series ended on a high - this is an excellent story with the usual build up of tension and menace. Without giving away too much, the end is not as final as it may seem. Pardon the pun, it offers a window of opportunity should the powers that be decide to bring back Sapphire and Steel (highly unlikely but I can always dream).

The atmosphere of the story is wonderful, but I could say that of all of them. Like most of its predecessors, the story is entirely studio-bound. For those with limited imaginations, the series has little to offer. I recall one magazine slating the series - but reading through the episode guides I came away with the realisation that here was one person who had not really watched the series and who probably harbored a wish that The Man from U.N.C.L.E. was running to this day. Assignment Six offers a tantalising glimpse into the strange universe that Sapphire and Steel police. Previous stories had featured entities that use Time, in this story we encounter rivals, another group of time agents who seem to have little care for correcting faults in time - a sort of anti-Sapphire and Steel.

It is unfortunate that Carlton haven't gone to town on this series. The DVD releases offer little more than the original VHS releases - they are almost bare bones with only a handful of static features. Not to mention the fact that all six stories have been spread across two box sets, so the series are mixed together. All 4 episodes of Assignment Six are on the third disc of the three which comprise the set.

There is no option to play all the episodes. When you reach the end of an episode you are returned to the menu and must select the next one. And the sole subtitles are in English only - of course, the series was not that big a success, but nothing damns a series more than the faint praise this DVD release represents.
