Chain Reaction (1996)

Chain Reaction is the kind of 90s studio thriller that grabs you by the collar and doesn’t let go, marrying big-city momentum with a smart, anxious sci-fi “what if” about clean energy becoming the most dangerous commodity in the room. Andrew Davis directs with a craftsman’s confidence, turning Chicago into a playground for muscular chases and close-call escapes that feel satisfyingly physical, not weightless or cartoonish. Keanu Reeves brings an everyman urgency that makes the scramble to survive feel immediate, while Rachel Weisz adds grounded intelligence and calm under pressure, giving the film more pulse than its premise alone might suggest. It’s not a hard-science think piece and it won’t win over viewers who want subtle, slow-burn conspiracy drama, but if you’re in the mood for a brisk, well-mounted action-thriller with a sleek 90s edge, it’s an easy watch.

Chain Reaction is clearly aiming for a slick, mid-’90s “wrongly accused” chase thriller wrapped in a science-fiction hook about clean energy, and on paper that’s a solid crowd-pleaser. The problem is the story keeps piling on twists and conspiracies that don’t feel earned, so instead of suspense you may find yourself distracted by how little of it makes sense. It leans hard on familiar genre beats—run, hide, get framed, trust no one—without the tension or character depth to make them pop. If you’re mainly here for a straightforward Keanu Reeves action sprint with a few decent set pieces and a likable pairing, you might get enough mileage; if you want smart sci-fi or a tight thriller, this will likely feel like a lot of noise for not much payoff.
