Warning Sign is not trying to be everything to everyone, and that focus is exactly what makes it work. The world-building is meticulous, but it is the characters who carry Warning Sign through its more ambitious moments. An accident occurs in an ultra-secret government biological weapons laboratory spreading a sinister bacteria. The human element stays intact thanks to Sam Waterston and Kathleen Quinlan, who anchor every scene. It was released in 1985. The world-building is meticulous enough to sustain multiple rewatches, with details early on that only make sense later. It knows exactly what it is, and does not try to be anything else.

Warning Sign is satisfying on multiple levels — something to watch and something to think about after. It rewards viewers regardless of what else is in their watch history. A contained runtime means every scene is doing real work. Watch for Sam Waterston in particular — the performance elevates the material. Satisfying on multiple levels.
