This is a very good re-telling of Mobile Suit Gundam, with this volume starting with the fall of Side 7, and the re-entry to Earth, which is a pretty good stopping place for the volume. Some of the plot alterations are interesting, like Garma's base being in LA instead of NYC, and Char launching a commando raid on Luna II as well. I gotta say though, considering how successful the Luna II attack was, I'm surprised the war isn't fought with more of those, and less open battles with Mecha.
This volume is also considerably more bloody then the show is. Now, to be fair, the TV show is just that, a TV show, and there are limits to what they can get away with (even Fist of the North Star had to show all their head explosions in silhouette). Still, it's enough where it definitely shifts the tone of the work a little bit.
I'm definitely looking forward to reading volume 2.
