There's no actual child romance. A 16 year has a crush. That crush jokes with him, steals his hat and is then gone for the film.
A 16 year old talks to his grandfather about their crush when the grandfather asks.
That's all. None of that is strange or extraordinary. It's incredibly insignificant and perfectly normal in real life and films. The only difference is that this is a boy having a male crush.
That's it, about 1 minute of the movie is causing all of these 1 stars
