I don't get it

Rating: 2/10 (29 March 2019)

Two stars for the actors who mostly did a terribly good job, especially Lupita with her psycho-double and Shahadi with her frozen mask of a devilish grin on the face of her double.
That's it.
I'm sorry, I'm from Germany, so maybe I don't get the racial history behind it. Obviously it's a big deal and I have no problem with african-american lead casts in non-stereotypical roles. This should be "normal" in movies. This shouldn't be an exception. But is the storyline really that good that this receives such a high rating? Is it now time that critics has to like this because otherwise it could be reffered to as a derogatory expression? Are people liking this despite the story just as a reflexion how pleased they are with the cast and the roles?
I'm from a minority from migrant workers, I was born and raised here, so believe me, I understand racism to a certain kind of degree.
And I am a movie geek and the most I laughed at the "Home Alone" referrence joke but other than this I didn't get the story at all. I think it was filled with plot-holes all over and was just poorly written.
The end was such a desaster I don't know where to begin. So I don't get it. And I think that the people who think they got it, just don't know, that they really didn't get it at all.
