la regle du jeu speaks for itself as well as a technical masterpiece,it beguiles you with it's attention to detail & the easy way it moves from comedy to tragedy ,farce,theatricality & above all the humanism of the piece .no one in cinema nailed humanity as did renoir.
but it demands to be seen again and again as it can't be understood with a couple of viewings as it is so ambiguous.
maybe some don't get it but to me it is an obvious work of genius by a genius (maybe it's too close to home for some who knows?) i don't but i do know a classic when i see one.
welles,luc - godard,truffaut,resnais,chaplin,bertolucci all 
agree on that one!...cheers
