Time travel comedies are not that easy to make. This does mention one of the most successful and entertaining one, that interestingly enough also is from France: The Visitors with Jean Reno. It became a series of movies, something that will not happen with this one. It's not that it is a bad movie, it's just not a really good one either.
The premise is pretty simple, the characters get introduced and it's a bit fish out of water. Except it's very predictable and you might have a hard time feeling sympathy for the characters. Maybe you won't at all, maybe just for a few scenes, where they really don't handle their situation well. Supposedly grown-ups but with major issues. There is material here, but it does get a bit buried. Still it's decent enough to entertain to a degree
