It is a story of survival and sisterhood. How circumstances make us behave altogether differently and how love can come to rescue. It also sheds light on how the world order affects us.
It fails to bring out a few themes that could make the storyline more real.
With the emotional chaos, rationality takes a backseat sometimes.
Also, since it deals with adolescents, it brings out the reckless attitude they exercise and how it forms a part of growing up..
Worth some time...
