Given the sheer volume of characters, a pretty good job was done of introducing everyone and even focusing on a few, already introducing the sub plots. Right after that is the number of well known names in this. Also noteworthy is that there are two Supernatural actors in here too: Jim Beaver and Katie Cassidy (almost unrecognizable here with dark hair). The murders are suitably shocking and apparently random, but I also really enjoyed the introduction of the previous murders on the island, the few flashbacks have been extremely intriguing and not the usual slasher images, instead the bodies were hung on display in the trees.
A very impressive beginning, I already know I'm going to watch the rest.
