I agree that it paints both sides as silly, but it does so incredibly badly. This is evidenced by, eg., the comments on Letterboxd, who all seem to either think their outgroup is lampooned (yay 5 stars) or their ingroup is slighted (grr 1 star). The movie set out to combat division and failed catastrophically. At least that’s my charitable interpretation. It’s also too long, lol.
