It's not that good

There was too much Matt Walsh in it. He's not a good actor and has little to no charisma. The movie would be much better if he had simply let these grifters reveal their mad beliefs rather than injecting himself into confected situations in an unsuccessful Borat-style attempt to elicit reactions. It didn't help that he was sometimes (badly) playing the role of an earnest DEI acolyte, while at other times being obnoxious and goofy, such as at the dinner party. He was cringey, but not in a funny way. Showing a series of well-researched interviews and participation in DEI activities would have been much more effective, but only if Walsh could come across as sincere. I'd give it a 6/10 for being brave enough to tackle the subject matter, though it had the potential to be much more. Louis Theroux would have killed it.
