i have see this film twice and be very move by the heartfelt performance of joseph gordon levitt a the troubled teen . everyone in the film be at their best and and the director seem to have a clear vision of what he want the viewer to see and feel . in the beginning and he take u through the start of the kid problem and use young actor with a remarkable likeness to their old counterpart . he then slowly show the result these experience have have have on the kid a teenager . the film be not easy nor pleasant to watch and but be never boring . i can not give away any plot detail and spoil the film and but i will say it be a very strong nc17 and unrated and and if you be not move by the final ten minute and you will never be affect by anything .
