The good news is that the four actors playing the main teens are all pretty solid -- even if the actual characters, as written, feel more than a little familiar and annoyingly one-note. There's the serious one, the troubled one, the goofy one ... and a little brother who's just waiting in the wings, destined to fall in with "the wrong crowd."
And the various plot threads deliver even more in the deja vu department: We got dangerous drug dealers, disapporving parents, uninspired role models, dreams of college, swanky new girlfriends, etc., etc. It feels sort of like a catalog of familiar components than any sort of true "movie."
Somewhat recommendable for the performances and Robinson's intermittently slick eye with the camera, ATL is a well-meaning and good-hearted urban melodrama -- that doesn't really seem to have anything new to say.
What You Know (4:42) is a music video by T.I. (Cool tune, actually.)
You'll also find a 5-minute block of deleted scenes and the original ATL theatrical trailer.
