Sinners is an elite movie-going experience. The quality of cinematography and score is made for an Imax theater with digital surround sound. The horror scenes are really well done, though the story is more action and drama than horror IMO.
It's just a great movie. But in terms of horror discussion, I think the way Coogler portrayed the vampires is the most interesting part. He took typical tropes (ie: you have to invite a vampire inside) and used them along with the story to make some really tense scenes.
But he also threw in some new concepts. like having the vampires share memories kinda like a hive mind. I'm not sure I've seen that before in a vamp story.
It's a great example of how writers can take tropes and use them to their advantage. What the audience already knows about creatures can be used to fast track certain parts of the story and juice up the tension.
