This Gundam Seed Astray series, like the original manga, deals with a lot of backstory and explains several things that the anime doesn't touch on very much.

While the storyline is good, the artwork is too rough and course. I often have trouble discerning what certain objects are, and at other times, an object will seem to change size from one frame to the next.

However, this manga also features a gundam that only appears in Astray R called the Regenerate Gundam. As the name suggests, this gundam can actually fix itself in the middle of a battle.
