Damn, you guys are making me miss England and not miss it all at the same time (I miss the place in general, but I don't miss being months behind America on movies and TV shows). Still, I'd take England over the U.S. any day of the week. At least your country respects stage acting.
Anyway...
Sawyer is definitely my favorite character on the show. Yeah, he's a bastard and a jackass, and maybe it is a little cliche that it's not totally his fault, but I think audiences are drawn to him because everyone knows how it feels to be an outcast and if it happens to you enough times, you eventually get to the point where you WANT to be the outcast because its the only thing you know how to be. But what makes Sawyer even more interesting is that he does have the ability to charm people and con them into thinking that he is trustworthy, yet he actually prefers to poke fun at them and piss them all off. So in some ways, by acting like a prick 23 out of 24 hours in a day, he's actually being more honest than if he was being nice to them.
Ironic, huh?
