That was lost on me but now I understand! My parents smoked them at one point!
Films and TV programmes that you have not seen for a number of years bring back fond memories. The Prisoner, I recollect, was on a Sunday evening. The white BALL that captured escapees was very frightening at the time. I bought the box set but when I came to view the first couple of episodes, it did not have that "buzz" and I felt somewhat deflated.
Possibly it is a mistake to go back and look at films we loved in our youth. Another film, which I thought was fantastic at the time, turned out to be very disappointing - "Sink the Bismark!"
The special effects have come a long way. Now they can digitally create dead actors! I find that quite disturbing.
