I am a 100% anglophone who stumbled along with Parisian french for a few years in high school, so I am not fluent but I 'get' a fair part of the dialogue (I've actually been using this show to improve my comprehension and learn the Quebec idioms and accents.) I have to say this is a really delightful family sitcom, and while it is basically a series of short gags as another reviewer pointed it, it's thematically cohesive and extremely well done in all regards. And, it's very funny in a pretty wholesome kind of way (though granted some of the subject matter and dialogue would raise a few eyebrows in prime-time English-language TV.) All the actors are very capable, but Daniel Briere and Anne Dorval are particularly adept at portraying the challenges of parenting in a very realistic yet humorous way.
It's amazing what Quebec television industry manages to turn out with what I assume would be a fairly limited budget due to its relatively small audience -- particularly since you rarely ever see any more than the series' five main actors in the majority of the episodes. English Canadian TV producers could definitely take a lesson or two from Les Parent.
