This story is about effort, stubborn and determination. This is a life game changing for this family. Tennis Trainings are an important part in this movie because you can see how this family pulls together to get a better life and escape from the neighbourhood they are living in. During this trainings/ negotiations with agents/ clubs you realise how hard was for this black American family. 

Will Smith as father role is well played and very believable and how difficult life  this father had but no matter what he stand up and keep going for her daughters. 
Mom’s role is incredibly well played for Aunjanue Ellis-Taylor, giving the strength that dad has not at the end of the film. 
Williams Parents, in the film, they were training hard her daughters but also giving the best education they could. 

It is and emotional and inspiring film.
