Excellent!
I'm not fully sold on the ending, though it isn't anything less than good either way, but the rest of
'Mystic River' is quality. The cast are superb, whether that be the main trio of Sean Penn, Tim Robbins and Kevin Bacon or the supporting Laurence Fishburne and Marcia Gay Harden. Bacon and Fishburne make for a terrific buddy cop duo, miles better than director Clint Eastwood's attempt with Charlie Sheen in the former's 1990 release
'The Rookie'.
The conclusion does I guess go in line with what precedes it, particularly with Robbins' character, but I'm not fully convinced by who is eventually unveiled as you know what. That's not to say it's a bad end, as noted at the top, as it's still entertaining no matter what.
