Godard once said that "The truth is that there is no terror untempered by some great moral idea.", and in Week End, I must warn you there is some animal cruelty and terrifying scenes (but how terrifying can fake blood be?), but it all has a purpose. Overall, he just wanted to create discussion, and he wanted to see people debate on the millions of issues in this film. So if you hate it or love it, that's what he wanted in cinema.
For next time, I'm thinking about watching François Truffaut's "Les Quatre Cents Coups" (The 400 Blows) starring a really young Jean-Pierre Léaud, and I'll promise you it's not political this time.
