saw this at our local film festival . feel very heavily influence in term of style and presentation by britain trainspotting the main protagonist haircut and cachetic physique and overdose scene and etc . still and the lead can give ewan mcgregor a run for his money in the acting department . of course and the story be completely different from trainspotting . well construct and develop story . one can feel the main character escalate paranoid and eventual loss of control a circumstance and event get too big for him to handle . be there really such a character in real life . poor chap .
