Did the director fail to see the irony.

Rating: 3/10 (2 December 2009)

OK so the premise of the ending is that, although the justice system is flawed, you cant just kill people to get your own justice and you are becoming what you hate and it will lead to your demise. So how does the director explain then that Foxx, the supposed good guy of the film, instead of using the justice system he represents to hold Butler accountable for his crimes, does instead just murder him in his cell. How does that make him any different to Butler. But Foxx murdering someone is apparently OK and he goes on to have a happy life watching his daughter play the cello. Murdering someone because they are murdering because of the murder of other people. Irony anyone.
Its a real shame but the stupidity and lack of bravery in giving the film the ending it deserved just ruined it.
