I saw this movie years ago, but loved it from the beginning... It took a little getting used to the French, but after 10 minutes, you don't think about it... I was lucky enough to see it on an HD channel a while ago and it's just beautiful - definitely worth buying on bluray!
The fact that it's based on true events, just makes it even more interesting, and since it takes place in France, it would have been completely wrong to have it be in English...
I highly recommend anyone to see it - a perfect mix of love, sex, friendship, hate, and violence...
