Les Cinq Diables, from director Léa Mysius, begins with intrigue but never fully delivers on its concept. Adèle Exarchopoulos is magnetic in every scene, and Sally Dramé rivals Hushpuppy (Quvenzhané Wallis) as the cutest kid ever. If this movie shines for any one reason, it is that we get to spend 96 minutes with these two.
The story and storytelling, however, are the weakest links. For a good chunk of the film, the story sort of meanders without any real sort of tension, presumably to tease out the mystery. Some plot points end up going nowhere, the climax that gets supernaturally pieced together doesn't pack the punch it seems it is going for, and I think a lot more could have been done to bring the themes home and make it far more powerful. In a way it reminds me of a Jacques Audiard film in the way it unloads a lot of rich theme but does not tie it down neatly for the viewer--which may be frustrating for some audiences and thought-provoking for others.
Les Cinq Diables is an ambitious film that lays decent groundwork but never seems to find its footing. It may leave enough for some interesting discussion on the interface between sexuality and relationships through the eyes of the innocent, but its clever approach more often gets entangled in subpar storytelling and a loosely-threaded plot.
Watch it for the cute kid and for the goddess Adele. Skip if you desire a more cohesive narrative.
