It is a bit repetive, with the main there by Trevor Jones being played about 92 times throughout the movie. But it's a great score, composed by both Jones and Randy Edleman. The theme played during the final chase/fight sequence, based upon a a peice of music called "the Gael" by Dougie McLean, is one of my favorites of all time. I love that movie! I love the fact that all of the characters are doing what they think is right, from their own perspective, and I love the dry sense of humor. There is a sense of nobility and tragedy to this movie that has always stuck with me, and the fight sequences influenced every single epic that has come sense then (I particularly like the way Hawkeye moves swiftly and easily through the battles, almost as if he is slowmotion but everyone else is not, taking out each opponent one by one, then moving and as he cuts a trail to his objective.). I think Michael Mann is a freaking genius.
The only thing that frustrates me about the score is that, in the DVD director's cut, Mann has removed the Clannad song "I Will Find You." Artistically, I see whay he did it it always felt like something tacked on by the studio - but it's a beautiful song.
Incidentally, back to the subject of Micahel Bay, there is a hysterical editorial, supposedly written by Bay, on this week's edition of theonion.com. If you are unfamiliar with The Onion, it is a newspaper parody, and while it often crosses the line into being too crude, much of it is very, very funny. Check it out.
