Story: Basically think of this as Survivor (the TV show) meets anime. No seriously, that's what the plot revolves around which is people stranded on an island and they have to survive except this time its a deadly form of survival where people can, and will, die. The story description in the MAL page here describes it best. IMO, the story was simple enough to follow yet interesting enough to continue. Various conflicts would happen and it was enjoyable. There are some scenes of sexual violence so if rape and implied rape makes you feel unease, then be warned that there are a few scenes early on, but you don't see the full act of it happening per se.
Outside of that, the story is basic and simple but that's not bad when compared to animes with stories so complex that you have to read wikia, the manga, online posts, or just rewatch it many times, just to understand it.
Art: I swear I had this vibe that the art style for some scenes and some people were like SnK. The style was fine. Nothing in particular to say about it. The people were interesting in looks, some had distinctive features like a large forehead (well it appears that way), braids, tats, mega breasts, etc. And speaking boobs, the fanservice was surprisingly mild. Sure the main female has nice DD or E cup breasts, but there was only a few fairly mild ecchi scenes, so the mood was kept fairly serious.
Sound: Not much to say here. The music OP and ED were great, BGM was fitting mostly. Of course the use of Half Life Crowbar-hitting-metal sound was there a few times.
Character: Weakest part of the show. There were plenty of characters that COULD have had more interesting things to them, but it was usually explained through flashbacks and would last for just one episode. The main two characters were lacking in detail but at least they established how they were loosely connected before you find out later how they truly met.
Enjoyment: I really wanted to like this, I really did. I found myself enjoying it from the near start, all the way to the end, but then when I saw the last few minutes of it, i realized that they were going to do a Deadman Wonderland move on me and end the show (and series) on a ton of cliffhangers and with many things left unanswered. With that said, I don't know if I would recommend this to anyone because I would hate for them to watch it and then say "Wow, all that just for an ending that isn't an ending?".
