Jacob Wilson’s review published on Letterboxd:
A film about terrorism in France that's actually saying more about youth, rebellion, and consumerism. Nocturama starts slowly, skating along with little dialogue as a group of disparate teens enact an unknown plan. Slowly we see the execution of a terrorist act, one that we are given little insight into, why have these characters in their late teens and early 20s pulled of this stunt? It doesn't really matter, instead the movie spends most of its time focusing on the aftermath, not in a Reservoir Dogs - like violent mystery of what went wrong, but by giving us a look at these passionate youth as they hang out in an expensive mall, waiting out the evening so they can make their escape. There's no answers given, little motivation, but slowly layers are peeled back, and we see the desperate passion, regret, and immaturity at work in each of them. This is a masterclass in editing, pulling together plot strands while providing equal measures and clarity and ambiguity.
