Same here. There was something feeling so obviously off with Don't Look Up.. for me at least. Idiocracy did not suffer from this.. but Mike Judge is somewhat of an acquired taste I guess.
I never saw it but Scott Alexander's review made it sound like the writers of Don't Look Up were themselves idiots, who wanted to send a political message but couldn't figure out how to do it properly.
