Though it may not be necessary to watch part 1 before part 2, it might make more sense to watch it since part 2 is the prequel to part 1. However, I watched part 2 before the first series. For me, it was not necessarily the smoothest of transitions. But the story is simple and basic, yet it conveys a sense of life as it exists. One comes to terms with who he is and the other does not. There are only two characters in this series and so the whole story is shouldered on the strength and conviction of these two young men.
