This has all the ingredients of a great gangster movie: three childhood friends (in fact two brothers and a friend) grow up in South Boston to become an FBI agent, a state senator and … Whitey Bulger, the notorious gangster. He’s offered a deal to take down the Mafia and … everyone gets tainted. This is missing a few story beats which would have made it a classic but the real performance here is by Joel Edgerton as the agent. And what’s truly astonishing is … IT’S ALL TRUE. Wow.
