The title "Supernova" is a metaphor for the explosive release of accumulated human guilt and emotion that occurs in the final scene.

The film is often confused with the 2020 drama of the same name starring Colin Firth and Stanley Tucci, but Kruhlik’s work is a distinct, fast-paced "documentary-style" record of a tragedy.

The film focuses on the "three unities"—time, place, and action—unfolding over just a few hours in a rural community.

Reviewers on IMDb describe it as "short, sharp and completely engrossing," utilizing a minimalist but high-impact approach.
