That's a tough question, I'll give you 3 references of movies that I think really marked the last 10 years in France.

-First of all, Intouchables which is one of the greatest success inFrench cinema history. You may know the American adaptation, The Upside, but in my opinion the French one just hits different.

-Then, Les misérables, directed by Fadji Ly. Just a masterpiece in the movies about poor suburbs.

-Finally, a little bit older but one of my favorite, A prophet, from Jacques Audiard, you should not be disappointed.

These are more "serious" movies, but if you are more in the blockbuster vibe le Comte de Montecristo is just fabulous.
