Liam's media product challenges some conventions of post-apocalyptic films while also developing others. It uses a dull color grade and desolate landscape to match the genre's conventions. However, it challenges the lone survivor trope by featuring two protagonists working together. The opening chase scene also brings something new rather than a typical slow start. While titles usually appear at the start, Liam's appear at the end to fit with the aerial shot conclusion. Costumes also reference conventions by appearing worn to indicate the characters' experiences.
