“Curvature” (** out of four) was a muddled time-travel thriller in which a young engineer (Lyndsy Fonseca) has to travel back in time to stop herself from committing a murder and is helped by a young doctor (Noah Bean) and pursued ruthlessly by two sinister cops (Glenn Morshower and Alex Lanipekun). Pulsating music score from Adam Taylor and Noah Rosenthal’s stylish cinematography are definite plusses but story never gets going and eventually decays into stale corn. Watchable on a draggy night but you’d just as well watch “Total Recall” or “Blade Runner” instead.
