The issue with this genre is that too many such movies come out and most have predictable endings. So it is up to the writer and director to come up with something that is scary and has enough twists and turns. In this case, however, the story lacks exactly that. Though the comedy works very well, the 'scare' and 'spook' elements are sadly missing and becomes very predictable after a point. The second half of the movie moves quickly but the first half could have perhaps been written better.
