Coppelion's gotten more enjoyable for me. The old man who caused the accident is a nice guy, and I like seeing the totally spies interact with him even if I don't like them very much(They don't seem to have a lot of personality, and I don't like the personality they have shown). The characters cry way more than I do, but it has gotten more moving. The old professor who wants to make amends for the accident and Ibara who wants to make up for her failures in the second episode are pretty touching. Their commanding officer has a nice moment too, when they come to pick the professor up, I had to blink a lot all of a sudden when he extended his hand to the old man.
Some parts seem dumb to me, though. I can't stand the girl who eats a lot. They keep on calling an obvious plane a crow. And Ibara has these speeches that I kind of can't follow. What's this supposed to mean, Ibara-senpaaaaiii? I understand the words that are coming out of your mouth, and I understand the circumstances around them, but I can't believe you're saying them. I'm embarrassed on her behalf.
I forgot to mention that Coppelion is also really COOL at times. There was a chase/fight scene in the latest episode where the girls drove through buildings on a jeep, fighting a stealth bomber with a missile launcher. And it looked very, very good.
