Antebellum needs a satisfying ending to match all the set-up, and it’s lacking one.
While there obviously is merit to handling a cinematic mystery with a subtle hand, Gerard Bush and Christopher Renz take that a tad too far with their ending here, as the questions you’re left with aren’t the kind that should be left up to interpretation, but instead address holes in the plot that need filling. Save for one super exposition-heavy monologue late in the movie, there is no real effort to address the important, big picture machinations in the story, and while the filmmakers deserve credit for lacing the background with interesting Easter eggs, they aren’t capable of performing the necessary heavy lifting.
