Matt Neal: Review: Source Code. The Warrnambool Standard, 22. September 2011, abgerufen am 28. September 2011 (englisch): „The search for some extra meaning at the end of the film does seem a bit of an afterthought, the pacing and repetition may put some people off, and the occasionally necessary exposition is heavy but this intelligent sci-fi-thriller is a worthy follow-up to Moon that marks Jones as one of the best new filmmakers around.“
