Threesome - Eine Nacht in New York

For some reason I was intrigued by this movie. I kept watching it thinking something would happen. Nothing happened. Halfway through it looked like something might happen. Nothing happened. I still kept watching it though, waiting for some grand revelation, or some insight, or some idea of what it was about, and I didn't get it. I waited for the plot to reveal itself or for there to be some sort of context to the story. There was none. There was no foreshadowing, there did not appear to be any conflict, there didn't appear to be a resolution at the end, either. This movie left me unfulfilled and confused. What is the point of this movie?? I have no idea. Does anyone know, and if so can you share with me what the point of this movie was?
