Amateurish is the perfect term to describe this affair. The film uses concept of a "self-help" book being utilized as a tool by characters as a MacGuffin and not that well. The script makes the mistake like many other films of using the idea of mental health as an explanation for character becoming a violent antagonist. Labeled as a thriller, the film has too many comedic scenes to not be placed in the 'comedy' genre as well. On those terms, it's not very funny and for the first hour doesn't even attempt to be a true thriller, building no suspension or tension. After that, it suddenly becomes a free-for-all with multiple attacks and kills. The film moves at a fine pace but it doesn't matter because the tone itself is all over the place. A lot of the films scenes only purpose seems to be to fill time as they add little to the plotline. The acting is below average. Both the sound and visual editing can be a bit wonky at times. I will not be revisiting this one.
