If memory serves, this is another episode where I read the novelised version before I saw the actual filmed one. Either way, I think the twist in this episode is easily predictable from early on, especially when the same hitch-hiker is being seen by our protagonist all the way along the road she is travelling.
Still, this is an effective way of using the Twilight Zone as an entity, as Nan Adams is still in constant contact with people all along her journey, even though that is patently impossible if the conclusion is the reality. Thus, by swerving in and out of the Twilight Zone the story meshes together well.
Despite this, I find my attention not being fully focused throughout this episode. It’s one where the story works well enough, but the lead character is played just a touch too much overwrought for my liking.
Rating: Stay off the kerb. 3/5
