The final episode of this strange 70's horror-ish anthology still doesn't really shed much light on what the series is supposed the be about, but it's a well performed, if perhaps overly bizarre story.
Fed up with the run-down old car, John (Terence Rigby) and his wife Susan (Pinkie Johnson) decide to dump the car on the other side of London. When they tell their friend Eric (Neil McCarthy) about it, he decides to visit it, to take a part he needs. He tells them the car isn't where they left it, but a few streets over. From there Eric, John and Susan see the car in various locations across London and, disturbingly, it seems to be slowly heading in their direction.
So, the performances here are, as I say pretty good. Terence Rigby and Neil McCarthy had a couple of hundred roles between then, often in smaller parts in some fairly major productions. Johnson and Rigby make a believable couple, who fill their free time training homing pigeons (which I'd assume is no longer central London's premier couple hobby). The pigeons coming home feeds into the idea of the car returning back to them, and is a nice, if not exactly subtle, bit of plotting.
It does require a bit of suspension of disbelief as it gets towards its conclusion, as the laws of physics are glossed over to make it to the downbeat end of the story. It does do good job of racketing up the tension across it's run time, although (and without spoilers) it was mostly dissipated by the scenes in the ending that did rather make me laugh.
I'm still no clearer to working out what "Tales of Unease" was supposed to actually be about as there didn't appear to be any unifying premise or themes. I'm also perhaps a little disappointed that the series wasn't actually scarier than it might have been and this episode is another that befits that criticism.
