Okay - I have been asked to cast a vote, but after all these years (I was 10 when I saw it) I can only pass judgement on how I felt back then. Being the target audience for this series, I couldn't wait for each episode. The series featured a bunch of school kids who for a number of contrived reasons (but plausible for gullible kids) got involved in espionage and all things 007. One episode sticks in my mind where the kids are locked in a cupboard while the bad guys have left a burning-candle-under-the-rope type death for the kids who using vinegar, a tube of rolled paper and some baking soda, extinguish the candle-flame with CO2 gas. More of this scientific McGyver-type stunts were performed with absolutely no "don't try this as home kids" riders. Great stuff! Looking at IMDb I see none of the child actors turned in any heavy-duty roles in later life. This is a milestone series in my childhood and though the exact plots etc. remain vague and hazy, the feeling of excitement in watching the series is still very strong.
