textual anaylis

In Fish tank we see Mia's sister watching MTV cribs on the TV this is the signifier. At first sight this doesn't seem relevant but i feel this relates to her wanted to have that celebrity lifestyle. We see her live in poverty and her escape is watching MTV cribs , dreaming about that lifestyle of wealth this is the sign.  Another point that i feel has deeper meaning in Fish-tank is Mia's aim to free a tied up horse, this being the signifier. I feel this relates to Mia , like the horse , they are both trapped and victims of their environment. As Mia's boyfriend says how the horse was put down due to how old it was this reflects Mia's decision to leave as she doesn't want to be like the horse, to old and never to be set free, this is the sign.
