Now I really can’t say what this is supposed to be about, beyond the fact that loads of little plasticine men seem to be populating some highly-strung girders above a sprawling metropolis who are counterbalanced by a great big ball, like the one you might find in a cistern. Just how anyone got into this state of affairs in anyone’s guess, but suffice to say that even the slightest alteration to their equilibrium could spell disaster as some sort of gloop awaits them if they descend. It is good fun, though - especially when one is persistently told he has a phone call,  and those of us who remember Tony Hart’s loveable “Morph” might enjoy some of the simple expressions and acrobatics of these nimble little creatures. Maybe it’s best not to get too scientific about the plot and just enjoy it as a bit of mischief? I did.
