Good work done by KANNAN IYER.and well written by Vishal Bhardwaj.The story is like our childhood's witch tail told by many many times but the presentation is good.In the first half of movie you will see an very good combination of DRAMA,HORROR and ACTING.Imraan Hasmi (Beejoy Sharad Mathur a Magician aka BOBO) and Konkana Sen Sharma did justice to their roles.Some very good magic tricks are also watchful. When Gulzaar and Vishal Bhardwaj come together results a very good music album.Song "TOTE UD GAYE" and "KALI KALI AANKHON KA" are awesome,overall a good music.
Second half of movie is an un-necessary twist,in fact movie should end in first half itself.you will see nothing new happening in second half yet you can watch it for twist and happy ending like always happen in Hindi cinema.
Overall somebody telling witch's story in Hindi cinema first time with very good background music,with very good songs but with an very ordinary climax.
