Throughout the course of the film we follow Grey as he is has joined various armies in fights mainly set out to kill one another and his main goal is to become a full fledged citizen, that status can only be obtained until he advances beyond Class F Trooper status, we find out over the course of the film Grey's girlfriend Lips (in her pursuit for civilian-ship) had died years ago under the command of General Red. As all that happens his journey whilst tagging along with his partner Nova comes to a full conclusion with the world's computer structure Big Mama. So essentially the film's main focus with it's story is the advancement of a character trying to claw his way out of poverty and suffering to gain a chance of freedom.
From an audio perspective in regards to the music, the score by Goro Awami is both tense and rather minimal at best. Seeing as how the entire movie relies heavily on silence with only the characters doing their own thing that the only thing you might hear in it being music is 1 or 2 lyrical insert songs. The English dub though is where I think this stands out more, this is probably one of the Ocean Group's finest dubs and ranks up their among some of their well regarded work. Paul Dobson plays the character of Grey just right with adding a stotic and dry persona to the character but making him feel like a tragic soul, other Ocean regulars such as Scott Mcneil, David Kaye, Jaynse Jaud etc play their parts rather well which shows this movie on the English speaking side of things has a well assembled cast.
In conclusion, Grey: Digital Target is a forgotten gem that deserves more recognition. As an old school classic it's nothing "groundbreaking" but from a storytelling viewpoint it speaks a deeper message about the pointlessness of war and the untrustworthy behavior of authority and higher powers. A classic that deserves a DVD release and hopefully one day a revival, it's worth the recommendation.
