Once again, this is not a cute or whimsical film; the trench warfare sequences show the war in an authentically brutal light. Nonetheless, Jeunet's usual signatures (creative use of colour-grading, from the golden Breton countryside to the watercoloured-sepia-photograph effect in other shots, flashbacks, and the occasional mechanical/time-and-motion sequence reminiscent of Delicatessen or The City of Lost Children). The reconstructions of Paris in 1920 were quite impressive; I got the feeling that, in some ways, Amélie and its digitally-cleaned-up Montmartre was a rehearsal for the making of this film. I hope that when the DVD comes out, it will come with a feature describing exactly how the film was made.
The ending was quite strong too, though I won't say any more about that. Anyway, I strongly recommend this film.
