The TVI Take
AMC+/Shudder's six-episode adaptation of Victor LaValle's novel, with Dan Stevens involuntarily committed to a psychiatric ward stalked by something the staff refuses to name. Chris Cantwell (Halt and Catch Fire) and LaValle showrun under Ridley Scott's exec banner, turning the institutional setting into the season's actual antagonist — the show works hardest when it lets bureaucratic neglect carry the dread the supernatural can't.
The compressed episode order (six vs. ten in prior seasons) costs it some of the political nuance the source novel earned.
