John Oliver's new season kicked off with a spectacular episode on a dismal subject: whether or not there is such a thing as truth, why Donald Trump seems so poorly acquainted with it, and how it is that so many people have been dragged into the unfactual universe with him.
It's a combination of Trump not being very bright, being surrounded by pretty terrible people, and the usefulness of disinformation to attaining the trumpist agenda.
The episode isn't the game-changer that the Net Neutrality/Cable Company Fuckery was in 2014, but it's the opening salvo in a long war.
And, as always, it ends with a doozy of a stunt (around 21:50).
