Sorry to bump this up, but I just finished watching this series, so...
Well, for one thing:
1. Animation sucked.
2. Characters are a blatant rip-off of Gundam SEED. (But since it's the same character designer, well...)
3. Initial story was a bit bland, but it did get better a bit.
4. The romance in the story sucked. It's too damn cheesy.
However, the ending was kind of interesting, but since the site does state that they (Tia/Tea and Tokito) were thrown into the endless space of time (or whatever), most likely they're just repeating history all over again.
I, for one, will NOT repeat history all over again, thank you very much.
If EVER they re-make this Anime (e.g. animation similar or better than Code Geass), then maybe I'll watch it again... but in my book, 6 out of 10. It's just so-so.
