Goofs

While Jane is trying on a little black dress at a store with her mother, she is not wearing a bra. When she steps into the fitting room and takes off the dress, her phone rings. Her mother then pushes open the door, and Jane is suddenly wearing a black bra with a standard back band. There is no way Jane could have put her bra on again that quickly.

Creole people are black, nobody identifies as creole instead of black. What the writers failed to understand was that "black" and "African" are not synonymous, and the meaning of the word creole, and where Cape Verde is. Cape Verde is an African island, and the population is mixed race: African and European, which is the definition of creole. Which is why the people from there identify as exactly what they are.

It's black Americans that are weird, identifying as "African-American" like they weren't born in the States. (Nobody else in the world does that.)

Exorcisms are in no way therapeutic. People don't die from therapeutic treatments. It's a battle for a person's soul and often involves torturous methods to force the demon out of the body. People have been choked, starved, and crucified during exorcisms, none of which would be offered by any kind of therapist.

Expelling demons and malevolent spirits from a person isn't unique to Christianity, specifically Catholicism, but the term exorcism is. So exorcisms certainly are not practiced by "every culture". Most cultures actually don't have rituals to expel demons (because most religions don't have demons).

Poto mitan translates as "post in the middle" and is a literal post, in the centre of a voodoo temple. It is the centre point of the ceremonies, and a term used to describe Haitian woman, as they are the centre of the community. There's no Heaven in voodoo, so there's no pole connecting it to Earth.

Boubous have nothing to do with Christianity. They are a traditions African item of clothing, religion (especially a religion from a different continent) had no affect on African dress, or African clothing choices.
