“Satire is a genre of the visual, literary and performing arts, usually in the form of fiction and less frequently non-fiction, in which vices, follies, abuses, and shortcomings are held up to ridicule, often with the intent of shaming or exposing the perceived flaws of individuals, corporations, government, or society itself into improvement.”
I watched the start of the film (not yet to the end) and my conclusion was rapidly that the genre of the film is satire. The persons are caricatures, exposing common flaws to the extreme. That includes also the scientist - just watch how he explains the problem to the president.
I saw the film as a general criticism of the values and lacking rationalism of politicians and apparently also others (have not yet seen the whole film) - what happens in the next election is more important than a planetkiller hitting the Earth after the election.
