Given the cast (which includes Matthew McConaughey, Jennifer Jason Leigh, Eddie Marsan, Bruce Dern, and Piper Laurie) and the remarkable premise, this Detroit-set docudrama should have been a knock-out; unfortunately, it fails to make much of a dramatic impact. The title character is the teenage son of a two-bit arms seller (McConaughey) who goes from being an FBI informant to a high-profile drug dealer in the mid-1980s. No matter how far he rises in the criminal underworld, Rick can’t help making stupid mistakes (he’s only a kid, after all); the most incredible part of his story may be that he avoids arrest for as long as he does. Director Yann Demange (’71) seems uncertain whether to play the material as searing drama or black comedy, and so he gives up on establishing a recognizable tone altogether. More damningly, the awkward, arhythmic editing keeps one from enjoying this on a purely narrative level.
