For starters, let me just say that although I am an out-and-out Dean girl, I love Sam dearly as well. You can’t have one without the other; they are as much a part of each other as an arm or a leg. As Dean so eloquently put it, ‘there ain’t no me if there ain’t no you.’
I’d be insulting your intelligence if I didn’t start off by saying it was their looks that initially drew me into the show. However, early in season 1, I knew these characters were so much more than just their pretty faces.
I love their rabid loyalty toward each other and toward those they love. I love their bond, deeply loving without being mawkish and unrealistic – I love the way they banter and fight, just the way real brothers would.
I love Dean’s subtle intelligence. Dean is often thought of as the ‘dumb’ one, but nothing could be further from the truth. Dean may not be academic and full of book-learning like Sam is, but his street-smarts are formidable. You’d have to get up very early to get one over on Dean.
I love that underneath their rough exteriors they have hearts of gold; I love their overwhelming desire to protect others, even those who don’t deserve protecting.
What I love most about them though is that they are both deeply flawed characters, and that makes them easier to relate to. They have insecurities and faults the way we all do, but they also have a darkness and a recklessness that has been instilled by the life they have been forced to lead. Despite that, however, they still focus on doing the right thing for the right reasons, even if the means to that end isn't particularly pleasant; the road to hell ... and all that.
They are such well-conceived, well-written, well-acted, multi-faceted characters, I can honestly say that I have never been so emotionally invested in any other work of fiction, and I doubt whether I ever will again.
