Overall, I'd vote this a 7.5/10 film, if fractions were available.
I think the comments by L8Hatter (above) veer near the essential tone as to whether or not a person reading these comments might want to view the film. Nonetheless, I am rather more sympathetic than Mr/s Hatter, because I think the film is especially strong in one regard: directing.
I differ with L8Hatter re "We're supposed to believe that this tough, streetwise gang boss would be stupid enough not to see the consequences of his actions..." I believe that is an oversimplification of the presentation of a powerful figure near the end of his life not realizing how his strength and, indeed, bullying conduct of his life have kept him more than a little ignorant of the feelings of those in his own family.
While I disagree with L8Hatter's phrasing, "...the second half of the film becomes increasingly silly...", I agree that there is definite stumbling in the plot line about halfway through the third act, which is a hell of a bad place to have it.
All that said, the directing pretty much single-handedly carries the film. If one particularly enjoys that aspect of the craft, this is a should-see film. And if you haven't some powerfully better film to watch this evening, the character work, cinematography, 92% of the plot line, and definitely the superbly paced directing of action, timing and actors, mean you can make up your mind now.
