In order to create tension and suspense, Riff Raff skillfully builds to its climax sequence and then makes good use of that encounter. Before a 30-minute sail to the finish line, everything falls into place. The grand conclusion is expertly timed, edited, and staged. There are a lot of things that the shoddy first sixty minutes aren't. The movie's opening teaser sequence, which piqued our attention, is explained, along with disclosures, broken relationships, and attempts at forgiveness.
Regarding the conclusion, I am unsure of my thoughts. At first glance, it appears uncomfortable and difficult to swallow. However, there is something about one character's last statement that makes me question if it is really that straightforward. Perhaps I am thinking too much. In any event, this is a film that, unlike many others nowadays, saves the best until last. Therefore, Riff Raff provides for those who persevere long enough. I only wish there had been more interest in the buildup.
