Herrvonspeck’s review published on Letterboxd :
BlacKkKlansman wears a thin layer of comedy around a serious core of systemic issues of racism and oppression. This is a very American movie in every regard, beginning with the large list of references from Angela Davis to the exception to the prohibition of slavery in the 13th Amendment to Charlottesville to Blaxploitation movies of the 1960s and 1970s. For example, to understand Patrice's stance on abolishing the police altogether, you have to consider about 300 years of black oppression by governmental institutions like the police. It takes a bit of background knowledge to fully grasp this movie.
BlacKkKlansman has a few problems regarding its characters. All characters are flat stereotypes, including an ableist representation of a KKK member with low intelligence. There are only two women in this movie and both serve one specific function each. They are token characters.
Nevertheless, BlaKkKlansman tells an important story and makes sure everyone gets that the issues discussed aren't in the past, but still rampant in the present. And it does this while being decently entertaining.
