yep, it was a nice anime,, not groundbreaking, but deffintally worth the time...
I don't see any point for season 2, the plot was basically closed down in the end, the world is saved, and the good guys are in love... really not much left to do afterwards...
that is, unless you want to make it stellvia of the universe Z, and follow the adventured of what's her names (ponpon? something like that...) brother and what's her name's (the overly excited girl) sister, and that would suck!
well, not all stories have to have a shocking conclusion, it was an 'avarge' anime for a certain audince, and it did it's job well, you must move on to others... try Last Exile, it's also pretty nice,,,
