i think i have to watch this movie again and because it either pretty good or pretty average . it all depend on whether in the end and when we see the three murder again and this be what actually happen ( which would be awfully contrive and pretty bad ) or whether it another one of ishaan story and make up to save himself and the other two prisoner ( which would be a very interesting twist ) . there be clue to either interpretation and but it not really clear which of the two be happen . up to the end it a very good and taut movie with good acting and a perfect script while it just that the end and which i be not sure about and either destroy it or make it even well .
