For the general impression, I suggest first reading the review by DerOkashi. And now I will try to explain, why there are people like me, who like anime like Webdiver. As you read, Webdiver has a simple, generic and repetetiv story. I had no problem with that, because I love the setting. It reminds me of an old childrens book I own, "citties of tomorrow", where different assumption on future events are described, especially on how living will be, but also eg. the moon base to be build around the year 2000... Another reason for me to like the story are the charakters. Most of them having importancefor one episode and then just being nice ornaments of the background, there is a handful of interesting main charakters of which everyone has an interesting (but simple) personallity.
A point important for me: The parents of some of the main charakters play a role!
These interactions between charakters in the city of "Diverland" are the best parts of the series. Unfortunately these moments only make one sixth of the whole story, which mostly plays in "Magical Gate" (the digital world).

Magical Gate brings us to the artstyle. While Diverland, the real world, is well conceived, while the charakters are decently animated and designed, the mechas and the place they are in is really cheap 3D-dejection. There is actually one thing that looks good: The evil creatures of the second story arc. Their design is very creative!

But for me, I had to find out: It does not bother me at all. There are moments, I think "Oh Mein Gott, sieht das Kacke aus!" (Oh, my god, this looks crap!)... and these moments can get long; remember, this is a very typical mecha show, which means: Mecha Transformations!... Back and forth and with different variants and everything you would expect! This show is still mostly made to sell a variety of merchandise products produced by takara.
And now: When I sit there, looking at crappy animations of crappy 3D graphics for the 10000th time, you might ask the popular question: "Why?"

And I would not listen, absolutely absorbed by the music.
For this show of 52 episode, there exist each two opening and ending songs, aditionally some insert songs. Of these songs, four are under my absolute favourites of anime music and only one is really bad. The background music is not high quality, but I personally like it really much.

This piece of post 90's "primary-school-children-are-our-only-hope-to-rescue-the-world + mecha" series is one of the latest of its kind and suffers under a low budget and general lack of interest.
However, it was able to find its fans and has some interesting concepts.
Those who had fun with similar shows like erudoran-series, might want to give this a try. All those who dont know the genre, but wanting to explore it, should start with something else.

I express my gratitude to the members of Subdiver, having translated this show into english, korean and indonesian.
