Cage of Eden isn't a great manga. If you're looking for a piece of art that will stay with you, this isn't it. That said, it can be an enjoyable manga, depending on your expectations. If you expect fanservice, look elsewhere. The art is thoroughly mediocre all the way through, and none of the fights or characters look believable or realistic. This is especially true of the 'monsters' on the island where the main characters are stranded. Many of them look like modern animals with extra parts taped on. If you're looking for a thrilling story with good drama and exciting pacing, read Monster instead. But if you're bored, you don't mind fanservice, and you're looking for a survival story that doesn't get into boring lurches, this is your manga. Unlike some better manga, Cage of Eden stays consistently mediocre all the way through. It's not great- but it's usually entertaining. Like fast food, Cage of Eden is meant to be consumed quickly, so that sloppy art and repetitive story lines don't get in the way of enjoyment.
