Don't look up is just a moronic allegory attempt.

The meteor (cOViD) and the absolute idiots who are ignoring it!!!

It was designed so the sheep watch it, take a minute(or several) to figure out what the allegory is about (even though it's obvious) then think they are very smart and even more morally superior than they felt before.

Though I wouldn't put it past them to try using that as their next fear instigation attempt.
