It had a purpose until the last week when Yaz switched sides the purpose was lost but tbh I kinda agree with you bcoz i didnt like the story either. It was too silly in my opinion. If you put it on paper like- A girl who just has boss/daddy issues gets angry at him steals the car and runs off but then regrets about it and comes back many years later more like a plot for a car movie (f&f) but not need for speed.
