An absorbing drama that makes quite a powerful statement about the fragmented nature of modern life. It's a sort-of sequel to Haneke's 'Amour', but the tone is so different I didn't register this at first. The director has a tendency to impose ideas upon the naturalistic flow of a story, twisting characters to the point of implausibility. He can be irritatingly oblique, also. Another criticism is that 'Happy End' has an uncertain mood: it utilises the format of a social comedy, but the sense of underlying dread and menace makes it impossible to read as 'black humour'. Well-acted and impeccably filmed, though.
