The story was good, the plot development was too. But the horrors they used in selling were more of baits as there was almost nothing horrific or scary in the movie.
I enjoyed the movie. We used to hear Madam Koi Koi in my school back then. The movie made me remember.
For some of us that attended boarding schools, we lived the Madam Koi Koi myth in our early days before settling in. I found the first part of the movie really amusing and can not wait to know how Madam Koi Koi got into my school.
