I stopped after episode 9 and went to Reddit to see if anyone else thought the same. I really wanted to like it, because it's WIT Studio and FMA's writer got involved in the character design, but something in the story just doesn't click, I already don't like flashbacks but this one had heaps, and even have 'timeskips' without really any indication of it being one.
I feel like the story is torn between trying to be a serious, sci-fi, action anime, and I would have liked it that way (similar to the vibes I had with Eureka Seven when I was young), but it tried to be funny at times with the people making faces and suddenly cutting serious conversations. I think this is the first time that I watched an anime and everything is awesome - music, animation, drawing, character design, but once you tried to understand the story and relate with the characters, you see yourself grasping at straws.
