If you loved C'est la vie!, try So Happy Together
A bridge between a film you've already seen and one most people haven't. So Happy Together has roughly 5.9× fewer votes than C'est la vie! — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Olivier Nakache, Éric Toledano, and they both carry the playful mood tag, and they sit in Comedy territory. If that's the register that drew you to C'est la vie!, the second film will land in a comparable space — through a different lens.
What So Happy Together is
Here's a film about that most reliable source of comedy, the in-law. A man finds himself increasingly enmeshed in the life of his wife's family. His experience of them soon goes from tiresome to plain strange. It probably seemed funnier when they were writing it.
