“Body Cam” (**1/2 out of four) was an often jolting action drama about a morally conflicted cop (Mary J. Blige) who has just returned to active duty who soon finds recovered body camera footage implicating several of her officers in an attack. She then finds herself at a moral/personal/career crossroads about what to do about said footage while trying to resolve the supernatural forces behind all this. Hard-hitting mix of the hardships and brutalities that police have to deal with daily and others who engage in corruption and abuse but story unfortunately veers in the second half towards hokey supernatural elements which don’t entirely gell. Blige is rock-solid in her first lead acting role and her compelling and believable performance makes this worth watching.
