Ok, when it comes to the story, it's not too complex but it's still pretty good despite the cliches that it may throw in there. Matter of fact, it's those cliches that make the anime funny at times. Also, I like how the flashback episode was done. As viewers, we eventually learn that the Code Breakers are close but that episode really showed us their closeness. One thing that might be seen as an issue though is the fact that one of the Code Breakers is hardly mentioned and doesn't become important until later. There's also the thing with Rei's power... They never really explained how he got so strong at a certain point. They just said that his powers were "awakened". The phrase "An eye for an eye, a tooth for a tooth, and evil for evil" may be a little repetitive but I do think that it adds to the story. Other than that, there aren't many other problems.
The art looks a little cool. It's not too different from what you usually see in anime but the characters are nice to look at. There's also no issues with the animation. I don't recall seeing anything too weird looking.
The opening Dark Shame by Granrodeo really fits with the anime. The ending song also sounds nice. There's nothing really memorable about the soundtrack but it did add to the serious and emotional moments.
Most of the characters are good as well. Sakura may be seen as annoying, or even stupid, due to her strong sense of justice but she certainly isn't useless. Her sense of justice is both a flaw and a strength and the anime shows this. Most of the character motivations and actions are understandable, especially Hitomi's. In my opinion, Rei has the most character development. I don't think there's a lot of it in this anime, especially with Yuki, but the characters are likable due to their overall personalities and appearances.

Code Breaker questions what's good and what's evil. I think it did a good job with this. Overall, this anime deserves a 9.
