Good to see some people that did enjoy it
The show is definitely far from perfect, the only show that comes close to being perfect (for me at least) is 00, but I would still give AGE a 9/10 overall. The show for me really grew on me when Asemu's arc started. When the 3 protagonists were first made public, I was looking forward to him the most. To be honest, if it wasn't for Asemu, I probably wouldn't like the show as much as I do now. If there would had been only Flit's and Asemu's arc, the show could had been much better received. 2 generations a 25 episodes might had worked better. Kio's arc started good, but after he got the FX, he was just "there". I didn't really care for him, because he was overshadowed by Flit and moreso by Asemu.
The main flaw of AGE is, that it was just too ambitious. It tried to please everyone, but only pleased a minority in end, sadly.
