I have already vainly attempted to explain why you should follow your art and subsequently your bliss (Seriously, read up on Joseph Campbell if you haven't). But that is not enough to tell you why I read what I read and watch what I watch. And as we already know "because I love it" isn't enough.
The stories that hold my heart hostage are the stories of opposites. Not opposites in nature but opposites in humanity. I love the dichotomy between two men who stand at opposite ends of a spectrum but can still some of themselves in each other. At first I thought this was the literary idea of a "foil" but now I realize that it goes a little further than that. I love the idea of nemeses: two people who exist only to oppose each other and to clash and conflict. They are similar but represent something so entirely philosophically or morally different that it makes them enemies. I know it probably sounds like I am high right now so let me try to explain myself through some of my favorite examples.
Gabriel (Sylar) Gray - Peter Petrelli
My conflicted feelings regarding the show Heroes are fairly well documented at this point. But Heroes could fail as miserably as it wants to at this point and I would still watch it only for the ongoing relationship between Sylar and Peter. Of all the individuals who possess gifts on Heroes, Peter and Sylar are the most powerful. Each man has the ability to acquire and use any other Hero's "power". They are similar in this aspect, their physical appearance and even their bloodline but they each represent something entirely different. In order to use another person's power, Peter merely has to be in their presence and then recall their personality and the way they made him feel to utilize their power. Sylar, however, must murder someone, tear open their cranium and examine their brain in order to acquire a power. This difference highlights the dichotomy between what they stand for. Peter is a symbol of compassion and Sylar is a symbol for consumption
Batman - Joker
These two foes have been going at it for years. But I am not really a comic book person so I can only focus on the incarnations in Christopher Nolan's absolutely brilliant The Dark Knight. In the Dark Knight, Batman and Joker really should be the best of the fans. As far as the movie is concerned, they are the only two human beings on the planet who do what they do. They dress up in crazy costumes and take to the streets every night representing an idea truly greater than themselves and far greater than any "normal" civilian can. It is a lonely existence being the only "freak" in town but at least they have each other to spar with. And sparring is all they can ever do because as the Joker brilliantly notes Batman won't kill him because of his "code" and Joker won't kill Batman because he views him as a kindred spirit and so fascinating. But they can't quite be "kindred souls". For all their eccentricities and theatrics, Batman and Joker represent two ideas that are completely contradictory. Batman believes in "Order" the organized ways of society and law while Joker lives his life by only one creed: "Chaos".
Jack Shepard - John Locke
The similarities between these two Lost characters are fascinating. Aside from the obvious "they both crashed on a mysterious polar bear infested island", they share many other traits. Both are natural leaders of men, both have massively disappointing relationships with their fathers that they have had to overcome and both men are viewed with respect on the island. But they are polarizing figures. Despite their similarities, they just can't quite seem to get along. Jack is a Man of Science and Locke is a Man of Faith and this sets them on two sides of the same coin and in permanent conflict with each other. Their beliefs have strained the relations of everyone on the island and eventually broke the community into two groups. Every event that occurs are viewed through both of the perspectives of Jack and Locke. They represent the back-bone of the show and one of its main themes. But still, there is something tragic about the fact that they can't see just how similar they really are.
Those are the big ones and here are a few more that I appreciate.
The Matrix: Neo (Freedom) - Agent Smith (Bureaucracy)
Harry Potter: Harry Potter (Love) - Tom Riddle (Fear)
Unbreakable: David Dunne (Strength) - Elijah Price (Weakness)
Dexter: Dexter Morgan (Discipline) - James Doakes (Passion)
Lord of the Flies: Jack (Id) - Ralph (Ego) - Piggy (Superego)
And that friends, is how I intellectualize all the literature and entertainment that moves me. I encourage that you understand why you love something but at the end of the day: just appreciate it.
Only then can the explanation "because I love it" make sense.
