We have a bunch of attractive young outsiders who find each other and form a group - and in this group they feel that they belong. They bond over tales and acts of killing, as if it's the ultimate kick that makes them feel more alive then ever - better than drugs, better than sex.
And even if one of them makes a mistake that jeopardizes every member of the group, they will open their arms to him, hug him, and tell him that it doesn't matter, because they haven't given up on him.
What's the message here?
On the other side we have our protagonist, who - despite being portrayed by an outstanding actor - I feel is one of the least interesting/likable characters on the show (maybe because he's oh-so conflicted by his past and that's assumed to be the best ingredient for creating an interesting protagonist these days?).
I wonder how many people manage to sympathize with him more than they "sympathize" with the girl who killed her mother, the one person who's made her feel miserable and worthless for as long as she can remember.
Plus, it's just a matter of time until one of the people on the protagonist's side turns out to be a part of the network he's trying to take down. The hints haven't exactly been subtle. At least it can't be the African-American (the only one on the show), since he's already dead. [/sarcasm]
