The storytelling makes the movie worth the watch. The 5 mins monologue at the tail end, was a mini tale on its own. Although, somehow, it was difficult to sympathize with Nic. Throughout, especially during the car race, it felt like he understood what was going on, but did not want to stop it, coming off as wickedness. Is that the impact of the addiction? In any case, a few minor details were also overlooked. He and his step siblings seemed to stay the same age throughout the addiction phase. 14 months went by and, what?, they hadn't grown? Okay. That's enough review.
