Michael B Jordan's performance and presence in the film acting as two characters is undoubtedly the strength of the movie. The film in my opinion makes the attempt to deliver several different hidden messages especially during the Juke Joint Blues performance scenes that realistically could be a separate deserving story of its own that really does not at least directly have a connection to Michael B Jordan's characters or the vampire villain character but more with the inner spiritual battle with the guitar player. It would have been more informative if the film had more of a back story on the twins in Chicago along with scenes leading up to why they left similarly to the way it was done in Menace II Society and Interview with a Vampire. Along with that a brief backstory on how the vampire even ended up in that region of North America because it was only through a point of view that the Vampire could possibly be from across the Atlantic.
Also, the film displays inconsistencies in using traditional cinematic vampire protocols in the scene where a Vampire needs permission to enter a person's home just like in the 1985 and 2011 Fright Night films where there are distinguished scenes that portray that only then later in the film it seems that rule is just abandoned when all the vampires just run in the juke joint at will with no invitation. If an individual can recall far back enough about movie history its evident this film script is inspired by movies like the Assault on Precinct 13 (1976), Tales from the Crypt Demon Knight (1995), From Dusk till Dawn (1996) and in the story of the guitar player displays a resemblance to a young Blues legend Robert Johnson portrayed in the film Crossroads (1986). Overall is a great performance from the entire cast and it was great to see Delroy Lindo back on the Big Screen again he was in many good films like Blood in Blood Out and Clockers in the 1990's.
