The Dekalog is Krzysztof Kieślowski's critically aclaimed and powerfully engaing series of short films, each of which is inspired by one of the biblical "Ten Commandments". Over the last six months or so I have watched them all, having picked them up in a 2nd hand DVD shop; but having previously enjoyed Krzysztof Kieślowski's Three Colours trilogy.
The series consists of ten little relational dramas, but they are all linked courtesy of the fact that the backdrop for each of them is the same massive Soviet-era Warsaw flats. Although the films are not of even quality, and three of them stand out as being exceptionally good; there are only one or two that fail to be truly memorable. Here is a list of links to my reiews through the whole series.
