Interesting and entertaining. The English title is "Non-Fiction", but the original French title "Doubles Vies" (Double Lives) is more descriptive. The theme centers around writing and publication in the internet age, with provocative snippets of bracing conversation, some hilarious deadpan humor, and sexual infidelity as a metaphor for how writing cheats reality, all perfectly framed by the French language and the Gallic temperament. (Needs to be seen in the original French, with subtitles if necessary.) You could describe it as a fast-talking intellectual comedy, but it's one of those movies that can be as deep as you want to make it. I plan to rent it so I can stop/replay some of the dialogue. The director, Olivier Assayas, is a master of layered meanings.
