Thrilling and surprisingly original, Source Code nails the action genre with powerful performances and high stakes that keep you on the edge of your seat throughout. The peculiarities of each character keep you interested; Gyllenhaal provides an energetic, curious performance, Michelle Monaghan is open and romantic and then we get the operators Farmiga, who is human and sympathetic alongside a strange, unpredictable Jeffrey Wright. Overall it's a fun, easy and concise watch.
