Faded memories of watching this in 1978 when I was four caused me to buy this DVD. I used to think it was the cleverest show on TV because the program would end with the ATV sign-off, and, just when you thought it was finished, you'd get a 10 second reprise.
The marionette characters are endearing, and the dialog is witty, if not terribly P.C. The producers acknowledge that they really wanted to make a grown-up program..."Where's my battle axe? She's right here, Sire". What childrens TV program today would quote from Shakespeare, use words like "conflagration"?
The producers once worked for Gerry Anderson at Century 21, but the characters seem to have a different feel to say, Captain Scarlet. There is a "featurette" on the DVD with behind-the-scenes shots and interviews.
Buy it, for you or your kids, and you won't stop singing the theme tune.
