We used to watch this in French in high school! I absolutely loved the days when we'd walk in and be told we got to watch Maigret. They're kinda old, but way interesting, and we almost never knew what was going to happen. The episodes aren't predictable, which makes it all the more interesting. I hate when you know what's going to happen before it does, but I don't recall an instance where that was the case. It's totally worth checking out if you like a good mystery. And they really are great for French classes. I don't think we watched them in French with English subtitles like we did with other movies, but he's a French detective and there are a lot of French words and sites that are helpful to the students. We also used to write summaries of the stories entirely in French, so if you're a teacher, it's a great combination of comprehension and writing. If you decide you like these, or are looking for something similar, try watching Poirot. It's a series based on the stories by Agatha Christie. Same type of thing, but I'm partial to Maigret myself!
