Passable
This is not to bad, it's either making fun of anime or the giant robot anime. The art style is good enough (You can tell humans are humans and robots are robots, etc), color is vivid, backgrounds could use some work. The voice acting suffers from poor voice sync and volume (bad mixing overall.) The audio could be improved by premixing the background music with the voices so the voices are all louder than the background music, and it would save space in the flash file. The acting it self feels a little scripty, could probably be improved by simply taking out a lot of the pauses. One major improvement needed is a scene selection option at the beginning of the flash file as so you don't need to watch the entire thing just to skip back to a scene.
Overall it's original enough to warrant watching the prequel/sequels.
Good things:
Animation style, color
Meh things:
Voice acting
Bad things:
Audio sync, lots of long pauses in either speech or animation.
