I can agree with the main antagonist or villain is weak, but how can you say the motives aren't clear? HE'S A VAMPIRE!! It's cut and dry, there's no special or deep narrative motivation for his or any other vampire's actions. What do you think what a vampire does? We do not need anything to justify. That said, the so-called main vampire isn't the strongest, I agree.
Not really much of a spoiler because I agree nothing happened, but the Choctaw Indians was pointless but implied a backstory that we never received. My suspicions for this as well as any other nitpicks is that there's a HUGE director's cut that had to be edited out because of runtime requirements. This movie feels like a 4hr film that had to be cut down to 2hrs. There are several editing scenes that were noticeable to me that felt it meant to be longer. The Choctaw Indians is definitely one of them, I believe.
I suspended belief on vampire logic because there's vampires, mythical beings. I do get what you are saying, because you see several examples of them having hive-like minds and shared memories. But I do know that goes along with death, or so-called death since they're technically already dead and resurrected as undead monsters with the thirst of blood. Vampires aren't ever logical ever since the creation of Dracula. The Dracula story in itself isn't based on anything logical nor anybody try to think of it from a logical or logistical aspect. So, Ryan Coogler has a creative license in doing whatever he wants to tell his story.
I TOTALLY DISAGREE with the pivotal musical number of the film. And the opening sequence of the movie explains that scene, giving it foreshadowing to what can happen. For people who do not appreciate the power of music and how transcendental music can be through multiple cultures and generations, especially the power of BLACK MUSIC, I understand how it doesn't impact it to you narratively. However, it's WHY WE HAVE A VAMPIRE HORROR MOVIE to begin with. And the reason why the movie is called SINNERS. And I believe people who aren't religious, who aren't theologians, who are disconnected with any spirituality, I believe that scene going over their heads as it went over your head. And the main theme is how LUCIFER, the DEVIL swarmed around that juke joint. Lucifer's power is music and how that demon fallen angel uses music to attract the evil presence and corrupt the innocent minds. It's THAT SCENE that attracted the vampires. It's why Preacher Boy's father who's a Baptist minister condemned Preacher Boy's desire to play the blues because it is viewed as devils' music. The scene itself showcases how connected black music is. Black music is American music. We care the creators of all the popular musical genres. The bluesman is connected to the hip hop DJ. All international cultures are linked to its tribal origins. With THIS attracts the evil presence.
As for the overall theme, the movie is a love letter to the blues. The blues is paramount throughout the movie. The movie geography is Clarksdale, Mississippi. This location is well known for its area called "THE CROSSROADS". The Crossroads is the folklore of the bluesman by the name of Robert Johnson who supposedly made a deal with the devil to because the GOAT blues singer. The spiritual and religious allegories surround this film.
Clarksdale Mississippi is recognized as the location of the famous 'Devil's Crossroads' where Robert Johnson supposedly sold his soul to the Devil in return for fame as a bluesman.
