Most of the teams do not even interact with each other till the final day. There is always high tension as the competition is stiff but as you see each other dance in the end they cannot help but respect each other's craft and style.
Along with the scenes of awe inspiring body movements, the doc. also weaves in personal stories of some of the dancers from all the five teams. So, as you get to know the personal lives of some of the dancers, you actually feel the emotions of the dancers as they give in all their passion and dreams to their movements. While most of them are poor, shunned by "society" or a failure by most "standards", I think all of them have lived their dreams - of doing what means most to them. They may not be b-boying forever but I cannot help but be sure of the fact that this art they imbibed have made them a better human being. To dance like they do, you need dedication, commitment and love and in the process they learn just that; to be dedicated, to be committed, and to love.
A joke: How would a b-boy react if I wished him "Break a leg!"? I know it's lame! :D
