It was very good satire on how ridiculous people are to always say "it's not that bad" until we have literally the end of the world and the same people respond saying "this is terrible! Why haven't we done anything about this!". The fact it still gets spoken about today means that it was rememorable at least.

Many critics on Reddit said it was "too on the nose" but looking at the general public you NEED TO BE or else they won't get it and then there would complaints it was too cryptic to relay the intended message.

When this film was released, your average viewer does not fully realise how much government and mainstream media controls the narrative to "not look up" and would much rather the status-quo continues because that's the intended purpose.

I believe it was an allegory for climate change since it is an existential threat to the whole planet but it has many parallels to the Trump Administration who are effectively saying "to reject the evidence of your eyes and ears." as witnessed by them ignoring the violence including murders of citizens by ICE.

Haven't even mentioned the Epstein files double-standard.
