will sean pull the trigger? tragedy, 2 mutes

Rating: Null/10 (18 October 2003)

SPOILERS!!! I did not enjoy this movie, but i've thought a lot about it afterwards, and i too feel that it's a great movie. several viewers commented that sean's willingness to look the other way at dave's murder feels out of character. what do others make of the moment at the closing parade when sean looks at jimmy, points a finger like a gun and mimes pulling the trigger? is he simply referencing their childhood games or reiterating that he knows jimmy killed dave? i thought he might well be acknowledging that, sadly, he'd shortly have to come after jimmy.
many viewers note the film's allusion to classic tragedy, especially macbeth, with laura linney in the role of lady macbeth. i noted also that the revenge for jimmy's murder of ray harris comes via the hand of...ray harris (he's not known as junior). to me this feels not heavy-handed but classic greek or shakespearean fate.
by the way, there are not one but TWO mutes in the film: sean's estranged wife (yes i know she's not really mute, but she sure acts that way) and young ray. certainly these might represent the import of the unspoken past - especially dave's failure to confide in his wife. but i wonder if the mutes allude to some classical tragedy, and, if so, if erudite fan might fill in the reference.
