March_ts I'm thinking on moving to France for a few months (big decision!)
First of all: congrats on the big decision! I'm sure this is a very exciting time for you @March_ts and I DO envy you (in a good way).
I'm not a very good point of reference for French audiovisual materials, but I do know one awesome TV show that won an International Emmy Award as the best drama. It called Les Revenants and it's absolutely amazing (if you love dramas with some supernatural twist).
Very well acted, gripping story, and I think it might be helpful for French learners (although I can't assess the difficulty of language since I watched it with English subtitles)
You might also want to check out an excellent movie called "The Untouchables". A very inspiring and heart-warming story that will bring tears to your eyes.
You might also want to check out Luc Besson's filmography. Lot's of good movies in there (I particularly like Wassabi and Taxi)
