A Space-Opera in 3 acts, "Kiddy Grade" in my (humble) oppinion should rightfully be regarded as a Classic of the Genre.
Although, as many are quick to point-out, the show is off to a "Slow Start" [spoiler]Which apparently involves fighting five armed Cyborgs bare-handed and foregoing an inter-Planetary War[/spoiler], somehow it manages to never seem boring, if maybe a bit easy-going at times.
To that i have to attribute the copious doses of fanservice, splendid mecha graphics, and to a lesser extent the Classical Victorian style implemented in the artwork, from balroom-dances to Lumiére's schoolgirl *ahem* I mean work-uniform, which help to give the Series a distinguished look and feel.
In the Second Chapter of the Series however, the atmosphere shifts radically as things take a turn for the worst, and thus the actual Plotline is Born. From then-on things seem increasingly bleak, as you watch what you once regarded a light-hearted-comedy unfold into Drama , also there is less Fanservice :(
The culminal point of the series leaves much to be desired, with the writhers probably exhausted form all the plot-twists in the previous chapter, they resolve to use an unprecedented number of deus-ex-machina plotpoints [spoiler]The Show itself kinda' ends with one[/spoiler], but at least they didn't forget the Fanservice this time :D
All-in all Kiddy-Grade is definetly worth watching, and not just for the Eye-Candy, but also for the morally-enriching, if poorly-presented Story, and a Universe so vast and exotic, it would make many an RPG's pale in Comparison.
...If only they hadn't gone with Gonzo :(
