The two things that really worked for me were that firstly, Horowitz doesn’t set out to do in-your-face spooky, gory stories that you just knew from the get-go was going to end terribly. He makes use of alot of very common situations, situations where people would never expect something spooky would go down, situations which were day-to-day occurrences for many of us and for the characters, but one wrong move or one small detail gone wrong and everything goes downhill.
Shades of Final Destination! I just really loved seeing how each story would unfold. All of them were such regular scenarios, it really disturbs you and gets under your skin, because of how normal everything seemed on the surface, only to find out that there was something sinister at work beneath.
You could easily find yourself in any of these situations. methinks.
What didn’t work:
This wasn’t a very big deal, but I just felt that some of the stories could have been elaborated on further or expanded on a little to add more context. Some were quite short and it felt that a more well-rounded story could have been told if it were lengthened.
