These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Tomboy
Critical Research Failure: This movie pretty much states that all tomboys are transgender and Butch Lesbian. Where a Tomboy just enjoys doing activities or dressing in cloths that are more gendered to a guy but know full well they are a girl.
The movie does not state anything of the sort. It simply presents a series of events; motivation, sexual orientation, and gender identity are all in the mind of the viewer.
Truth in Television: Many of the behaviors in the movie are rather accurate, right down to kids trying to "find out" a persons sex by taking off their pants.
Unfortunate Implications: If you see Laure as not being cisgendered the film becomes riddled with this.
It pretty much states that Tomboy=Butch Lesbian, which is why many tomboys in real life are usually forced by their parents to act more girly because they fear they will be like that.
