As it has been said by others, this by all standards, not just as far French Canadian movies go, is a good movie. As somebody who grew up in Québec City I really appreciated how this movie really shows an intimate portrait of Quebec culture with all of its contradictions and beauty.
It showed how being an island of French in a sea of English does have an effect but that there is a definite Québecois culture which definitely bleeds into and mixes in with pop culture. For example the main character a young boy who is deeply conflicted with his sexuality is told he has the ability to heal people just by thinking of them if they are hurt...something which is uniquely Quebecois "old wives tale" The movie spans 2 decades or so, and the recreation of those decades from the house decor, to the music is really well done. The sound track shows in equal weights great Quebec classics along side such rock legends of the time of Pink Floyd and David Bowie.
The movie is great not because of a complicated twisty plot but rather really well acted and created characters. A very touching portrait of family life that can be appreciated not by just someone from that culture but supersedes cultural boundaries.
