The movie itself is great. It's based on the novel, Beltorchika's Children, with several major differences. I would've liked to have seen it more accurate to the novel. The biggest difference is that in the novel, Amuro's girlfriend was Beltorchika (the same girl from Zeta Gundam), and she was pregnant with Amuro's child. Unlike Chan, Beltorchika survived the novel. Bandai did not want Amuro having kids, especially out of wedlock, and they did not want Amuro married, because the fan-girls wouldn't like it. Aside from that, Amuro's Hi-Nu Gundam was also cut out, to save time. I don't know much about the rest of the differences, but I would still say this is a very good movie.
The American release, however, is trash. There's no swearing at all, things are translated wrong ("ikimasu" does not translate to "let's do it!"), and "Sieg Zeon" is translated "Hail Zeon" in both the subs and the dub. With a cataclysmic war resulting in over a billion deaths in the original series and many many more in series following, it's nice to know Bandai will be there to save the day, making sure that nobody gets hurt, or at least in the American version. Blah.
