"The Lonely" is a frustrating episode. I want to like it, but I got annoyed right from the beginning by the implausible premise. In the future, we're spending billions of dollars on rocket fuel and space travel to deliver supplies to prisoners who have been given their own asteroids?!?
Then, the mechanical girl part flys by. There's no real emotional development that makes us grieve or think at all when the end comes.
The episode isn't all bad. At the very least, it reminded me of this song, which I first heard performed by Bobby Bare....
