Thirteen is a eventful movie about the schools "good girl"(Tracy) being lead astray द्वारा a bad friend (Evie.)

I think that Evie acted the way she did because she had some serious trauma, we find this out when she tells Mel her life story. I think that Tracy also had some trauma, she acted out because her dad was never there for her when she most needed him. We can tell this because of the scene where her dad comes घर and how many times he's mentioned negatively.

I would rate this movie a 9.5/10 because it is accurate of how this would go.
