I would hate it if Billy Bat was adapted to an anime

For those who don't know what Billy Bat is, it's a manga by Naoki Urasawa and Takashi Nagasaki, the author of 20th Century Boys and Monster. It has a very similar story telling style - one that is intriguing, intricate, and impossibly good - while at the same time being so different from the other two stories mentioned. The difference being the use of comics and manga as part of the plot.

You see, Billy Bat has a few main characters, all of whom are artists and can see the titular and metaphysical bat, and they draw the bat out into the form of comics and manga. One brilliant way that the mangaka has implemented these things into the plot, is how he literally draws the comics in question out for us to read. Sometimes, he gives us pages of a comic within a comic, other times, he suddenly switches from the Billy Bat manga, to the Billy Bat comic that's within the manga, from panel to panel.
This type of narrative technique where he interweaves what the characters read and with what the characters do, let's us experience the same awe and astonishment they do when they read it.
A prime example of this, is how the beginning of the manga is the first publication of the comic 'Billy Bat', and the ending of the manga is the last pages of 'Billy Bat' to be published.

Now, onto my main point, of why I'd hate it if it were to be adapted into an anime.
At it's core, Billy Bat is a manga about drawing manga and the meaning a manga can convey. This is why the technique they use where they let us read a manga within a manga works so well. Sadly, this means that it's impossible to convey this to anime.
There are already examples of anime adapted from manga about manga, namely Bakuman, so it's not that it's because of the theme or focus of the manga that makes it unable to be adapted into anime, but the narrative technique I talked about before hand. I believe there's simply no way to turn that kind of amazing story telling into another form.
The smooth transitions from manga to in-verse comic is too fluid to be able to be imitated in the form of animation, and the techniques of the comics used in the manga can't be expressed through anime in a proper way.

Well, even if I do say that, I also think there are some parts of this manga that I think would do wonderfully in the form of animation, mainly, the parts where the bat comes to life.

And it's gotten quite long for a blog post, so I'll just leave it here for now.
