Gnometown Hero
We see the vampires in the opening scene of Sinners, when Preacherboy staggers into church and you have the flashes of the final fight at the club. There's at least one shot with fangs, which surprised me, since I thought Coogler would have wanted to sit on it.You may not really see much of the shark other than shadows and fins, but he is demonstrably present right from the first scene.
So, if anything, there's more vampire in the first few minutes of Sinners than there is shark in Jaws. We see Chrissy get killed while skinny dipping, but never see what's responsible.
