I have to agree that this is an underrated and very sorrowful movie. Behind the brain-teasing plot, the funny and sometimes brittle barbs, and the genuine suspenseful scenes, there is a sadness underlying it that makes it more than the usual thriller. Despite being witty, the actors stay deep in their depiction of the characters, specially the ill-fated relationship between the lovable losers Charlie (Cory McAbee) and the naive, trusting Teesha (Jahnika Blythe). There are several moments when the script reaches a climax and then suddenly interrupts it, but the screenwriter (here, it's first time director Scott Smith) always manages to bring it all back to the nature of the title thief. There are many minor details that those who appreciate smart films will find enjoyable too. Even the graffiti on the walls is extremely appropriate. I have only watched this movie once, and though I came away with a overwhelming sense of pity for Charlie, I was impressed that the story could have an emotional impact on me, so I say it's a keeper.
