After the carnage of series 3 - and an ending that was supposed to finish the series off - this takes place a few years on, with our team of resistors still going strong; killing, loving and exposing collaborators and general low-lifes. I love the way that the characters are given depth and how the viewer is lured into the intimate lives of the Poles, the Germans and even the Russians. Series 4 builds to a great climax and features one of the best scenes in the entire 65 episodes, where Rainer hops skips and jumps to the drink dispenser, whereupon he knocks it open with one bang. Truly, this is a comic moment and one that needs to be seen to be appreciated. I notice that series 6 is currently being aired in Poland and that series 7 - set during the Uprising - is currently being planned. Long may it continue.
