"Snitch” is a satisfying and surprisingly thoughtful action thriller. When his son is framed for selling drugs, Dwayne “The Rock” Johnson goes undercover for the government to reduce his sentence. The film plays its emotional cards too quickly, though, sprinting through an obligatory arc of daddy issues within the first thirty minutes. Johnson doesn’t have the acting chops to pull off the dramatic. Luckily, the film picks up the pace once the action starts, achieving a near–perfect rhythm of suspense and action. The twists and turns that drive the film are gripping, even if they’re not entirely plausible. Beneath the hood of this action thriller is an unexpected social consciousness—a commentary on the government’s misguided war on drugs, the young people whose futures are its casualties and the fathers who will do anything to protect them.
