I do understand why so many folks gave this film low scores. If you are a horror fan such as I and have seen the trailer bait which looked like a horror movie, you might feel cheated to find out that this is not even remotely a horror movie. Perhaps, it is deserving that the film receives low scores.
On the other hand, if you are also a fan of the 'drama' genre and watch the film from that perspective, you will enjoy it.
I do not know who decides to interpolate the genres a film carries within the description, are they IMDb people or Amazon people or whatever but the film, the script and the acting do not pretend to be a horror movie for sure. Therefore I do not blame the film itself for the false tag of horror.
The movie is the melodramatic life of the new immigrant to NYC, a Senegalese woman who works for a rich family as a nanny and takes care of their young daughter whilst trying to save enough money to have her 7 years old son to move in with her to the states. She is struggling with missing her son and working long hours for a family who demands a lot yet does not pay for all of her hours. And the longer it takes them to pay for her work, the longer it takes her to bring her son to NYC, and she starts breaking down in the distress.
It's a very well-acted film. I look forward to watching more of Anna Diop, who plays the nanny Aisha, in the future.
