For now, I can say something about Granblue Fantasy: Animation.
Overall, I expected it to be worse. The plot has been slightly improved, made more diverse, and in some places more logical, although in other places (the relationship between the main character and Lyria), they added unnecessary twists...
Actually, I was afraid it would be a complete disaster when I started watching the first episode. There, Gran is standing in full combat armor (well, not a full suit of plate armor, but still) and... he's chopping wood. And not with an axe, but with a hatchet. Heroes aren't afraid of challenges!
Ples and I also discussed that it would be good to have two protagonists in the anime – Gran and Jito. Since you can choose between them in the game. Of course, this would require additional work and rethinking on the part of the screenwriter; they could make them brother and sister, come up with differences in their characters, etc., but it would be worth it.
However, the final result is not bad. It could have been better; in many ways, this adaptation looks simply pale and uninspired. But from some moments, episodes, and some characters... I got quite a bit of enjoyment.
