Covering the events between 1975 and 1992, the movie is essentially about FBI’s arrangement with Depp’s character that was only used by the latter to further his criminal run.

Yes, Shakespeare would have had a field day. And so does Hollywood, namely director Scott Cooper and a top-flight ensemble led by Johnny Depp in a performance that reminds us, after a string of uninspiring movies, why he’s one of our most compelling actors. Yes, Depp is excellent. But the star attraction here? That’s the stunning story itself.

Watch it for Johnny Depp and Joel Edgerton’s masterful performances.

Watch this one if you’re a Depp fan. The film doesn’t really work without him. It’s good stuff, but nowhere close to what The Departed (also based in Boston) was.

After a long time, you see Johnny Depp giving a hard-hitting performance as this. To give him company is Joel Edgeton’s brilliant act. Laced with powerful performances and an engaging storyline, Black Mass is worth a watch for all those who enjoy mafia dramas.

Black Mass ends up being a forgettable film, with only Depp’s unnervingly artificial and lifeless face lingering in memory like the dregs of a nightmare. Go pick up a DVD of The Departed instead and you’ll get a better sense of why Whitey Bulger spawned a legend.

Overall, Scott Cooper’s direction results in a well-made and absorbing film, inundated with appropriate menace, but lacks the emotional core and sociological angle. Black Mass thus seems like more of a documented procedural routine.

Black Mass is the quintessential gangster film. It features equal parts of drama, action and thrill to keep you engaged. All this, backed by some award-worthy performances, makes the film a must-watch this weekend.

For a gangster film, Black Mass isn’t terribly exciting: It lacks the cheerful invective of The Departed or the masterful set pieces of The Town. Cooper directs with few flourishes, but he has a talent for atmosphere and for letting the tension in a room build. He never allows us to lose sight of how dangerous and unromantic a figure Bulger is, and how in awe of him Connolly remained.

The film has nothing that has not been explored in crime dramas. There are issues of loyalty and ratting. There are frictions over the issue of territory and if you cross it there are consequences. But the good thing is Cooper shows restraint. He doesn’t go for the overkill and lets the narrative and characters evolve in an ambience that is true to the disco-era of the late 70s and 80s.

The killings are swift, brutal and plentiful, executed with a businesslike chill that hangs over the whole movie. Black Mass is a better adaptation of non-fiction books than most, but the experience is ultimately as cold as Bulger’s heart.
