Okay, so I’m biased; I like Bee-Train, and their unique style. I’m not exactly sure how they did it, but they somehow caused me to really like this obviously flawed anime. I’ve seen lots of people give it bad reviews; it even turned into the “worst anime ever” for some. I’d like to say something positive about it, though.
A lot of things ‘clicked’ for me in Avenger. Its got a really interesting setting: Post-colonizational Mars, where no child has been born for ten years. The children have now been replaced with child-like robots called “dolls” (and finally we see androids who don’t look exactly like human beings. The dolls really look like machines in this series, which is really refreshing compared to the countless robotic harem maids that seem to be rather popular).
The soundtrack also is awesome. I seriously demand for the ALI-Project to do more of them for different anime, because their work in both Avenger as .Hack//Roots is really good. The OPs and EDs that they sometimes do for random shows might be good, they’re nothing when compared to the magic that they can do for the background music. The character-designs are also really appealing, but that’s to be expected from Bee-Train. I’ve never really been an animation-expert, but the three or four major fight scenes featured some great animation and coordination. The animation for the rest of the series was nothing special, though.
Then the characters. Unlike other reviewers, I really liked them. Some of them may lack background or reasons, but they’re well fleshed out through the course of thirteen episodes. Their character-development is very small and subtle (apart from Layla, perhaps), but it is there, just enough for such a short series. These factors, the music, animation, setting and characters, combined with Bee-Train’s direction provide a great atmosphere, which is despite all flaws, fun to watch.
Still, the flaws remain flaws, and this anime could have been so much better if Avenger took the time to answer all of its questions. This is another one of those series that suffers from the fact that its story was meant for 26 episodes, not thirteen of them. Because of this, things had to be sacrificed. In this case: the background information. How did people get on Mars? How can people breathe there? Where did Nei come from? These are just a small portion of the questions that this anime leaves behind. Even the ending continues to ask more questions. While it’s not as bad as in .Hack//Roots, the fact remains that this is a major thorn for this series.
About the question whether you will like this, you should ask yourself the following: do you like the so-called “Bee-Train Pacing”? If the answer is no, then stay far away from this series, because if you don’t like the whole atmosphere, you’ll be sure to hate it, especially with the relatively slow turns of events. I’ve also seen many people complain how the entire series is too confusing, though I didn’t run into the same problem (probably because I’ve been watching raws I don’t completely understand for a relative long time ^^;). In any case, I had a lot of fun watching this.
