As someone whose only vaguely familiar with the Harlock series, sat down and watched it. Visuals looked great, but fell flat for me a bit personally in terms of pacing/story.
Spoiler for spoilers:
Harlock discovering that only wealthy minority will be allowed to immigrate to earth causes him to blow up the earth...Harlock deciding that was a bad idea, plots to blow up the universe (his gullible crew thinks it's a time travel plot, it isn't). Harlock discovering cabbages growing on earth makes him decide to not blow up the earth, and instead faff about somewhere else. Something something about freedom.
Personally feel it could have used more
and less
