The only thing that really worries me of late is the general lack of discussion on this show. Maybe it is because of the slow releases, or that it isn't on TV, but in general it is hard to find anyplace that has decent amounts of conversation on this show...in English at least. Not many bloggers are reviewing it (that I can find) and few message boards have much in the way of discussion (or perhaps analysis) on this show. Maybe when it comes to TV in probably 2014 (in Japan) there will be discussion from the masses that get their anime from Chunchyroll or subgroups (even though the show is already subbed into English on the Blu-Discs...but those are expensive).
I think it's pretty much a combination of the weird release schedule, the fact that it's not on a legal streaming site, the fact that most anime viewers these days in the US have little to no knowledge of Starblazers or Yamato, and the fact that the show feels really unremarkable. It's good, there's no doubt about it, but there's no real sense that the writers and directors are going above and beyond because it's a remake.
