Why so great? Okay, it's three films for the price of one, with a cast of lovelorn judges, lonely emigres and grief-stricken widows searching for consolation in an unforgiving modern day Europe. But while Krzysztof Kieślowski's colour-coded trilogy works through the colours of the French national flag<!-- (if he'd picked South Africa, he'd still be making it), --> … and is rooted in liberte, egalite and fraternite, it's chock full of universal themes and emotions. They won't cheer you up — many of them centre on loss and sorrow — but just try not to be moved by them.
