It is okay if a sequel wants to be different from the original series.

It can have a different story, different characters or different themes.

But it should not go against everything the original series stood for, completely disregarding its message, unless there is a good reason for it.

This was the final straw for Eureka Seven AO.

In every other post I have pointed out what Eureka Seven AO did wrong on its own.

Now let me tell how you it completely ruined the ending Eureka Seven. (Anime, Eureka Seven, Eureka Seven Ao)
