I'm French and it's true that without the subtitles, I couldn't follow the dialogues in this regional language. The movie has some good funny lines about this strange french but overall, this movie is not worthy to be the 1st French comedy of all time! I didn't laugh that much because the movie is just overdosed with good feelings and the unavoidable happy ending! When the discovery of the natives is done, the movie is about helping romances and it lacks of originality! In addition, I didn't find the locations to be enjoyable as they are indeed a bit dreadful! The cast doesn't feel cool and natural so at the end, I won't repeat it the experience in a long time! It's true that France is the country where every region is attached to a particular culture that isn't french but for a better comedy about this reality, prefer the other movie of Boon or Mickael Youn's one!
