Well, IMO, it reminds me of Macross because it's about a large group of people from different backgrounds with different agendas (civilians, army, engineers, etc...) all trapped on this giant "alien" ship that's making it's way through space, and hopefully trying to get back to earth. Clearly the actual story-lines are different, and there's no mecha, but there are similarities (for me anyway). It's essentially a story about strangers trapped inside a giant "alien" space craft and trying to make life as "normal" as possible. I keep waiting for someone to suggest that they have a Miss Macross (or in this case a Miss Destiny) competition
I didn't say it had anything "to do" with Macross, I said it had a Macross-feel about it... as explained above! I can't believe you don't even see the slightest similarities!! If they ever made a live action Macross/Robotech movie, I'd love it to be dark and mysterious like this!
