This show has to be seen all the way through to properly judge it. It's a mystery that gives many pieces but doesn't show the whole puzzle until the end. I had a hard time getting interested in most of the episodes, hence the somewhat low score, because of how the heroes and villains were so hard to tell apart. Some of the heroes would do evil things for reasons you didn't know but none of the other characters in the show questioned while the villains seemed in the right. If you are in the middle of the show and question finishing it or haveheard bad things from people that didn't I recommend watching until the end because, unlike Lost, every question and inconsistency in the show is resolved in spectacular fashion. This is one of a very few shows I've seen that I couldn't predict and was satisfied with the ending.
