1. The movie was well-written, all elements on the film have their own part that contribute to the main story, no elements were used as fillers. At the start, you will have some questions like "who is the person who sent that thing?" and others. It will not feel at first that it will be answered later at the story. However, trust me. All your questions will be answered.
2. I like how the film progresses, from time to time you will feel that the film is nearing its end because there are many scenes that are worthy to be the ending. However, you will find out that the movie still continues.
3. It was filled with unexpected surprises and twists that will shock viewers. Take note that the revelations were scattered at the different parts of the movie. That's why every time you will feel that the movie is nearing its end, but before you know it, there will be another unexpected surprise.

Overall, I like this movie on how well-written this is. I like also the foreshadowing of the writer. You will be shocked at the story, but I advise that you pay attention to all of the elements displayed because those are the clues of what might happen. I will support the writer of this film; I hope that they will write for a short TV series with the same formula as this movie.
