From what I've seen, the extreme partisans on both sides don't like this movie, because it takes the piss out of all of them. The equivalent of antifa are shown to be a bunch of losers who aren't really much better than what they're fighting against. At the same time, the real world is shown to be more complex than painting entire groups of people with the same brush as extremists like Perfidia/Lockjaw and their ilk.
