That's my issue with the movie. People who don't believe in climate change aren't going to have their mind changed by a club, but need to be tricked with something subtle. Nothing entrenches someone deeper into their views then calling someone an idiot or telling them they're wrong. The movie represents everything that's wrong with how progressives and the "liberal elite" like McKay try and convince people to come to their side. If anything, this movie probably just furthered the divide. Having Leo in it probably didn't help, conservatives love to point out the hypocrisy of his private jet and yacht.
I say this as someone who worked on the Bernie Sanders campaign and have talked to him about how to change non-progressives minds, although I'm not sure he's made much progress either. Maybe a little more than McKay.
So who is this movie for, if not to sway climate deniers? If it was really intended to let a liberal audience grandstand and circlejerk about how they're so much smarter then everyone else (which I'm not denying), then I guess it did a pretty good job of that.
Edit: full disclosure as a movie also didn't enjoy it, jokes were kinda too on the nose. Also just felt and looked like a Netflix movie, kinda plastic. Idiocracy was way funnier.
Exactly haha, I get enough real life traumatic validation if I turn on the news for a second or look out my window
