I've honestly never seen it... But judging from My Anime List's reviews, it's pretty damn good. A lot of "10s" I see. Also...
1. It's a mecha
2. It's by Bones
What can go wrong there, right? The thing that would discourage me would be the 50 episodes... xDDD I hate animes that go over 30... Death Note and Code Geass are exceptions xDDD As well as Gundam00 and Monster... So basically, I just have to find the right anime... But whatever, 50 episodes is kind of a lot... I'd say go for it though and finish it.
