Well, it's three episodes in, and looking good. The mecha are pretty badass. The fight sequences are quick, clean, and non-repetitive. And not hide nor hair of the classical masked villain that's been standard since Mobile Suit Gundam. In fact, there hasn't really been anyone who fits the category so far, and the Gundam pilots don't cleanly fit the title of good guys either. Rather, it's from the perspective of the pilots, two senior warriors of the three earth nations, and a few civilians who each see Celestial Being's drive to bring peace by fighting both sides of a battle field in their own way.
This series has potential. Maybe even more than MSG clone Gundam Seed did.
