This manga was brilliant. The story gets you hooked fast. The characters were all developed well and just watching how all these very different characters deal with not only the trauma of their past but this horribly terrifying situation makes it an interesting read that both makes you think and cringe at the same time. Not for people who are turned away by gore or sex. This manga will make you smile and even laugh at times and make you want to cry at others.
If you have seem the movie... this manga is still a great read because unlike the movie it has time to delve into the histories of all the characters as well as show you part of each character's journy on the island.
