2.5, actually. How is the film called a psychological thriller ? The psychology is not fully explored and honestly, there's no suspense in the end (other than the loose ends).
Fahad Faasil is brilliant, superb. Great on all production fronts, but the script has too many holes and so many loose ends, the "fabric" is almost frayed in the end.
It appears the Director quit the movie after a brilliant, gripping first hour and then amateur movie buffs finished the movie. Literally, finished it.
