Is he as great

Depends if you like his style of films or not Jones70.

For me he's one of the greatest French filmmakers. La Silence De La Mer, Les Enfants Terribles, Bob Le Flambeur, Leon Morin, Le Doulos, Le Deuxieme Souffle, Le Samourai, Army Of Shadows and Le Circle Rouge. All Classic films imo. He's definitely a all time great.
