First, I apologize in advance for this rant. Second, since it's about the ending of the anime D.N.A², here's a nice big SPOILER WARNING. With that out of the way, I really didn't like the ending of D.N.A². I refer, of course, to the last three episodes released as a separate OVA to end the series.
Banner of the Stars was extremely good, continuing the high level of quality I enjoyed in Crest of the Stars. Epic plot with real sci-fi, superb characters and acting, and a very classy soundtrack. I don't know why this series is so underappreciated, but I'm definitely looking forward to watching Banner of the Stars II. And what's this I hear about a fourth series? As long as they don't screw it up royally, I will be most pleased.
