Yes, I agree C.R.A.Z.Y. is, for me, one if not the best french Canadian film in the decade or more.
Et oui, Ben, the film make me think about Ang Lee's "Icestorm" for the mood. The casting was just perfect for all the characteres.
Also Ben, you did not mentioned how good the music choice is and just perfect to give the mood of the 60's and 70's; may be it is for me, I'm born 9 days after the main charactere Zac.
A must see for all film lovers, you won't regret it.
p.s.: You can be prood of this one, no doubt.
