Dark Angel TV Series (2000 - 2002). A genetically enhanced human on the run, who has a good heart, but is a thief by trade. Another show that should have lasted longer! Jessica Alba and Jensen Ackles were both on this show.
"In case you haven't caught on by now, this girl's gonna do what she's gonna do no matter what you or anyone else says, so you've got two choices: back off or pitch in." (This is still one of my fave tv shows)
