Cav Gil’s review published on Letterboxd:
Duncan Jones is really good at these tight little sci-fi thrillers with like 2 or 3 primary actors.
He's got an eye for making these slick and thoughtful narratives. But while not as good as Moon, Source Code is still rock solid and works with its time loop premise really well and I like the setting of this one with the claustrophobic train carriages.
