This movie is garbage.

They changed too much of the basic plot.
One of the biggest revelations of the show was that Gamilons were humanoids. The movie changes that.
Half the space combat scenes take place inside the yamato and they don’t show the combat.
Everytime the Yamato gets in trouble the wave motion gun is used, sometimes shooting at unseen enemies that blow up and are never seen
The crew dance around the bridge giddy like school girls when things go their way. It’s very unmilitary like.
The English subtitles include a good amount of R rated swearing so if you thought to show this to your young kids you wil be disappointed.
The overall story is super mellow dramatic with tons of hand wringing drawn out scenes of contemplative decision making.
They also had a little speech about the Yamato “sailing out to bring hope like it did in 1945″ which I found insulting. Hope to who? The Japanese aggressors who raped and murdered their way across Asia? The ones who murdered 100,000 (NOT a typo) Chinese civilians as “punishment” because a handful of Chinese helped Americans avoid the Japanese troops after the Doolittle bombing of Tokyo? Japanese atrocities during WW2 have filled volumes. The least they could have done would be to show a multinational crew on board, something Star Trek did 50 years ago, at the height of the cold war. Do the Japanese not understand how evil they were just 2 generations ago?

Bottom line, this movie is garbage, front to back.
