Z.O.E. 2167 Idolo takes place a few years prior to the events of the series Z.O.E Dolores, i, and is centered on the "Deimos Incident," an act of terrorism by the Mars revolutionaries.
The BAHRAM army pilots Radium and Viola are the best in their class, and have such have been chosen to do spearhead testing on a new type of weapon; Mars hopes this weapon will liberate them from the UNSF's (United Nations Space Force) tyranny. This new technology called the "Orbital Frame," is powered by an extremely rare and powerful source of energy known as the Metatron ore.
Well, as the synopsis would imply, the story for Idolo occurs before the events of the ZOE game. If you've played any of the games you'll immediately recognise the main protagonists of the series, i.e that related to the development of Orbital Frames. Anyway on with the review:
Story (7/10): I gave the story a seven as I think it flows nicely but as you can imagine for a 55 min story, it does lack the breadth of a full movie. However, the story is believable and really gets into the emotions of the characters. It also lends some understanding to the background of Viola's
character and you can get to see why Viola is so bitter in the ZOE game.
Art (6/10): Nothing particularly groundbreaking but does its job effectively enough.
Sound (8/10): The music shares most of the characteristics of the games in terms of style and fits in nicely with much of the action of the film.
Character (6/10): The characters develop quite well considering the length, but perhaps not quite enough to really get to the motivations of the characters.
Enjoyment (8/10): A quick astute dose of good quality anime, so I would say the enjoyment level was quite high.
Overall (7/10): If you're a fan of the ZOE game series then I would highly recommend this if you want to get the background into the origins of the Orbital Frame. Even if you've never the played the games, it's still a highly enjoyable OVA.
