First of all, "Get Out" is not just a "black" film; however, knowing Hollywood, we can expect to see hundreds of knock-off movies based on the "black" horror theme now it has been proven that money can be made from the African American movie clientele.
You could easily switch out the characters and still have a decent movie. The African color adds a special layer of introspection and fun.
The movie employs all the popular tropes of a horror film: boyfriend meets strange family, a party with weird guests, freaky parents, and a basement were the blood and gore reside. But we so seldom see this genre with black faces that is like feeding raw meat to alligators. There is a frenzy of excitement. The producers exploited all of our "race porn" stereotypes -- i.e., Guess Who is coming to Dinner , Blacula and OJ.
This is good movie to see. Be prepare for the tsunami of black horror flicks to come.
