"Sins" is touted as a "remake" of the original series, but that's a fallacy. What it actually is, is a story so utterly disparate from the original that the use of familiar names and faces seems to have been the result of a combination of laziness on the part of the designers and a desire to boost the initial viewership by feeding off of a pre-existing fandom. The characters who "return" in "Sins" are not at all like the ones they were cloned from - in Luna's case there is no similarity whatsoever, which is a shame, because Luna was my favorite character in "Shinzou Ningen."
Even when I cooled down and resolved to evaluate "Sins" on its own merits, rather than comparing it to "Shinzou Ningen," it still came up lacking. It seems as though the creators got together to come up with a collection of evocative images and scenes, and then strung them all together with a flimsy, poorly developed plot cluttered with ill-fitting elements. The anime is rife with trite symbolism, and does its level best to constantly hammer you with angst, without bothering to be remotely subtle in the execution of it.
Actually, there's a fundamental lack of subtlety on most levels of this story's execution; where it's most damaging though is that as the story progresses it becomes overwhelmingly preachy; and that, more than anything else, I could have done without.
Despite that, I can't exactly call it a _bad_ anime, I think anyone who likes this style of story will probably find it reasonably entertaining, and the art and animation _are_ beautiful, but if you're looking for a great anime, this isn't it.
It's a pity though; I would have loved to see what a faithful rendering of "Shinzou Ningen Casshern" would have looked like executed with modern storytelling aesthetics.
