As previous reviews make clear, you either go with it or not. I have a very high tolerance for challenging cinema but even I thought at first, this is a daft French graduation film, sort of thing. But it got to me, it got to me, and in the end I think it's one of those films which pushes at what the medium can do - that is, what cumulative effect it can achieve on the viewer. It's neurology not narrative.
And for a sucker for The South like me, an immersion in Lisbon. The warmth (inferred), the sea, the elegant compactness of the built environment.
If Amazon permits, I'd like to ask if any Lusophone reading this can identify the Camane track over the opening titles, and the one that we see him singing; also the gorgeous Alsina Duarte song over the closing credits (so as I can buy them on Amazon, naturally! The CDs are there.)
Because . . this is really visual fado, the clue is that soundtrack. You can pull an Anglo face and say "silly!" - or you can sit back and think and feel.
