What I found interesting was that they always juxtaposed Jack and John. At the beginning of the series, Jack led with his head and John followed his heart. This often led to conflicts between the two. However, as the series moves on, Jack becomes a little more involved with his heart and what he feels is morally right, while Jack starts to doubt his beliefs and starts to think with his head. The two characters are still juxtaposed, but they seem to be [i]almost[/i] in the opposite spot that they started out in. I think John is one of the most interesting characters because, when the series started, he was definitely a \"good guy\". However, as more and more was revealed about his past and as John became more and more obsessed with the island, we start to see him in a new light. We start to wonder whether or not he is \"good\". That\'s interesting because the Others take the \"good\" people. A common theme of the show has always been good vs. bad vs. evil and whether [i]anyone[/i] is good. There are a lot of religious references in the show. I find that very interesting. I was kinda upset when they killed off Mr. Echo because the religious aspect he brought to the show was really intriguing. Well those are my thoughts on the show. I think the new season starts sometime soon, but I\'m not sure exactly when...
