So. I finally finally saw Infinite Ryvius about 8 years after it was released stateside. to think I wanted to watch this when I first got into anime. If I watched this after watching Evangelion my mind would have bee utterly blown. The nightmare fuel in this show is enough to last for years. From homicidal religious zealot schoolgirls to gangrape (it's implied in one of the episodes, atleast), and megalomaniacal teenage boys in big robots. As well as a huge military conspiracy intent on covering up your survival and trying to blow you up. All of that and I'm sure some people would call this a teen drama about growing up and learning to cope. I would, but this is anime, so its okay to call it a teen drama. I wouldn't have it any other way and it's why I watch it.
Onto the characters. Without getting into too much detail, because I don't feel like it, I don't think any boring characters exist in this show, save for Neya, and the Aiba brothers. Even then they weren't too bad, just not as interesting as everyone else. Everyone changed a little, even the side characters and the joke characters that had little to do with the main story, went through changes. the clearest examples would probably be the girl in the dinosaur suit who as the show went on, started losing parts of her costume until she was down too just a sleeve by midway through the series. The second half was her recovering each part until she was whole again by the end. And then there's the naked guy. He started the show naked with nothing but a throw pillow to cover his manhood, Eventually he moved onto a lion-cloth fashioned from a towel, then he even got a name and a shirt, but still no pants.
What really surprised me about this show is it actually had a decent, thought out ending unlike many anime where it just ends because they caught up to the book or the studio ran out of money to write a proper end for a show. It's not a great ending, just a well thought out one that has a definite conclusion.
I almost forgot to mention one more thing about this series. The music: Both the opening and the ending gave me somewhat of an oldschool anime feel, which I tend to like. That's just me I think. I just happen to like old anime music better. it doesn't give off that same melt your teeth, moe moe feel. In other words, the music doesn't sound overproduced or run through a a synth to make up for the singer's talent or lack thereof. I'm not saying that didn't happen either way, but it doesn't sound like it. A couple other tracks you hear have a definite hip-hop feel to it. the eycatch atleast, it has what most assuredly sounds like a loop from Biggie Smalls.
