ToneThe film plays its high-concept thriller premise mostly straight, with a knowing wink at its own absurdity that invites the audience to enjoy the ride without taking it seriously.
The rideThe series maintains high tension and suspense from the first episode through to the finale, constantly escalating the threat.
StructureTold in linear order with a single-location train setting and cutaways to the agency control room, but no unusual structural devices beyond standard serialization.
Episode formatThe series tells one continuous story across all episodes without case-of-the-week resets.
Season formatThe series is ongoing and the first season covers one self-contained train crisis; future seasons are expected to bring new arcs.
