Blue/White/Red: the movies

[RunDownHouse]

I saw these titles come up in the recent DVD thread. I've never heard of them, so I looked them up and read some brief plot summaries online. They sound interesting, but I was wondering if any of you OOTiots could give me a bit deeper of a review. I don't want to invest this $11 in three movies I'll end up hating. Alternatively, suggest some other really good foreign flicks.

FWIW I don't often watch foreign films, but I've loved the ones I have seen, such as Goodbye Lenin and - of course - City of God.
