You want a gourmet hamburger, you go to a gourmet hamburger restaurant, it might cost you $20 or $30. You just want a quick snack instead? Then go to a fast food joint and buy a $2 hamburger. It won't be very good but it will quench your hunger for a short while.
That's how it is with Amazon's Blumhouse movies, like this one, "Black as Night". They are like a cheap hamburger, you'd never tell anyone how great they are but can help you pass the time.
This one is set and filmed in New Orleans, much on the West Bank area known as Algiers and much in the New Orleans Garden District. It is the aftermath of hurricane Katrina and many displaced, homeless are being recruited into Babineaux's zombie corps. It is best enjoyed almost as a spoof of horror movies, there are a number of funny scenes. The acting is fine, especially Keith David as the main vampire. The cinematography is excellent, the movie is not to be taken too seriously.
Most of the very negative reviews here say very silly things, like how old the actress is playing a teenager. Things that have no relevance to the story or the quality of the movie. It isn't a great movie but it isn't a terrible one either. It is entertaining for anyone looking for a lightweight vampire movie. I enjoyed it.
