Any movie's success is dependent on its Story and depth of screen play and the dialogue which the caricatures speak. And those screen shot truly stick to even after you leave the theatre, and they converse with you. Those are the movements which makes the movie watchable. Why does PS still speak to us, What makes us think" how nice would it be, if there was a time machine to fly to that Era". Its the refinement which we see.
Speaking rude/ using swear does not make it up to international standard ,, and he had tired to compensate that by showing it grossness, which seems to be hypocritical By brutally killing and giving close up shot of those he thought he might acclaim credit. Its like shocker effect!! Some might like it!! and its totally their independence.
