The mostly true story of the rise and fall of South Boston gangster Whitey Bulger.

Rating: Null/10 (14 May 2016)

I was able to watch this at home on DVD from my public library. My wife chose to NOT see it, she doesn't care for this type of movie.
First the title, I was able to find this online, "Black Mass" is a phrase, which essentially represents "a perversion of the Catholic mass,'' is a metaphor for the FBI's corruption, with Bulger as the devil. "It plays in the idea of an unholy alliance.''
Johnny Depp received a Best Actor nomination for his role as Bulger, complete with prosthetic makeup which, according to those who knew Bulger in the 1970s and 1980s, was eerily reminiscent of Bulger himself. The look, along with Depp's acting, was genuinely menacing to some of the cast members, according to the 12-minute feature on the DVD extras.
Is it a good movie? Well yes if you believe that it is primarily factual. As we see in the movie Bulger leaves Boston and travels the world under assumed names until captured some years later and he is now in prison for the rest of his life. He disputes the content of the source book, as do several other key characters. Depp requested, through his lawyer, a face-to-face with Bulger, but was denied, reportedly because Bulger was not happy with the story being presented.
The movie has lots of bloody violence and foul language throughout, as might be expected of ruthless mobsters. I choose to believe most of it is factual and as such is a fascinating look inside organized crime, informants, and FBI connections.
