I agree. While Faiz may have been a huge mess with more plot holes than you could count, it DID work as a emotional roller coaster.
Some said that Yuka's story was depressing, but over the top. I really don't see that. I have known many boys and girls who have shared the same fate as Yuka did. Getting beat up at home and in school, being in the shadow of their older brother/sister etc. It is not uncommon, especially not in Eastern Asia.
We are always presented to Japanese families as the most perfect and happy families in the world, but the fact is that quite many children in Japan are under a huge pressure from their families, and some even get beaten.
It does not happen to everyone, but it happens.
As for Ryu in Agito. I have some mixed feelings about him, because while I did feel sorry for him, his constant lack of luck almost became a running gag later on. They even joked about it in Ryuki, where his short cameo consited of being beaten up by Asakura :laugh:
Through the whole show, it was like "Let's give Ryu something that will make him extremely happy, and then we will take it away from him and punch him in the nuts!"
He was tormented and eventually killed, ONLY to be brought back to life and go through the whole **** again. Evil, Inoue... evil...
Heck, I almost expected his puppy to get run over in the last episode...
