This is a Thriller episode that divides those who watch it. Personally, I enjoyed it. If you ignore the main premise which is a cross between 'Christine' and 'Herbie' and watch for the whole especially it's script, direction and acting then it is a lot better than others - take for example S2 E4 with it's poor stage sets and script.
In her second 'Thriller' appearance Donna Mills adds glamour but also plays her part perfectly and without over acting a difficult role to make believable.
The episodes runs at a pace that builds up a tension and is always intriguing even if the ending is made over complicated.
