What is going on with Casey Affleck's accent?

Rating: 1/10 (10 June 2008)

'Gone Baby Gone' with Casey Affleck, Ed Harris and Morgan Freeman and directed by Ben Affleck I found to be a pretentious load of garbage with too many messages on morality.
Not an entertainment and was glad when it was over. Casey Affleck seemed only to be speaking in monotone throughout the entire movie to disguise his dreadful attempt at a Boston accent that sounded more like a Brooklyn accent (thought not much like that either.
Furthermore, Ed Harris' wig was the worst hair prop I've ever seen for a bald actor and the incredulous behaviour of his was almost as unrealistic as Casey Affleck's character becoming judge and executioner of a paedophile who was pleading for mercy following the murder of a child.
Although I am personally abhorrent of cruelty to children, I am also dead against pretentious crap like this film saying it is okay to perform a vigilante killing of a paedophile who has murdered somebody else's child. In my book this would make Casey Affleck's character every bit as bad as the evil paedophile who succumbed to his cold-blooded vigilantism.
Please feel free to watch the film and form your own opinion, and I would be interested to hear from other people with opposite views. But I'm telling you now, this film is totally crap, and as a previous reviewer has pointed out, Casey Affleck and some other actors are incoherent and desperately require subtitles so we know what the hell they're saying.
On any other day I would simply have walked out of the theatre, but I had to give the film a chance to at least see if Ben Affleck had been able to redeem himself before the closing credits came up. But... it didn't happen.
