Sure, but it’s too little too late.
The main ethos of South Park is “if you care about something you’re a loser”. Which is fine if you are a show that airs when things are, generally speaking, going well. The moment serious issues entered the picture, whether climate change or 9/11 and GWOT, they fell flat on their face.
And it took them twenty years to get up.
And that is why they are legacy losers.
