I would say radhika aptes best movie and acting till date.Movie is set in a apartment with same old horror stuffs but never feels same old.Directors has palyed his part really really well.Hatsoff to his direction hes capable of bring freshness with same old tactics he knows how to make a movie at his best with just direction and acting.Radhika aptes is suffering from a phobia( her minds develops illutions and halucination of it own) and her struggle to understand and fightbacking the situation is appreciable.I would just say tighten your seat belt while watching.Really good
