“Just Mercy” (*** out of four) was an absorbing true story of determined civil-rights attorney Bryan Stevenson (Michael B. Jordan) who takes up the case of a wrongly convicted inmate (Jamie Foxx) who is on death row and works to have his case overturned to the bigotry and bias that resulted in his conviction. Two powerhouse performances from Foxx and (especially) Jordan make this a must-watch even as it covers some familiar ground and territory. Well-realized and directed by Destin Daniel Cretton based on Stevenson’s memoir of the same name.
