Is The Last Man on Earth on-topic?
By all accounts it sounds post-apocalyptic enough:
The year is 2020, Phil Miller (Will Forte) is seemingly the only human left on Earth after a deadly virus swept the planet one year earlier. An average man "who likes Star Wars, Twinkies, and sex", Phil searches North America in his RV for other survivors. After a long journey, Phil returns to his hometown of Tucson, Arizona believing that he is Earth's last surviving human. Just before he attempts suicide out of loneliness and a desire for a female companion, his prayers are answered, and he meets Carol Pilbasian (Kristen Schaal), an irritating and obnoxious woman
Bear in mind, that you should focus on the speculative fiction aspects of the show.
