All the Bright Places plus some shed light

I have already written about All the Bright Places, but the more depressing part. I am going to shed some much needed light upon the two characters fascinated by death. The first thing that comes to mind is why reviewers find death an off setting topic. Especially when all readers can think about is how the main two characters want to blast themselves off the tallest building in their town.
  On the brighter side of All the Bright Places, there is a very complex relation ship within every character of the book. Most notedly the Finch and Violet who end with falling in love (not a big shocker). Even though the book can be interpreted as grey, by the end of the book each character has painted themselves a much needed rainbow.
