Is there a source for this?

A Twitter/X post. The link's on the page. Waiting for an official source & confirmation, which could be a while.

Can you send me the link? I can't seem to find it

Yes! KOTPOTA wasn’t perfect, but it was really good and a good start to a new trilogy.

Yes, it was, in its own way.

Kingdom is not a decent film; it's a great film, just as good as Rise, Dawn, and War. Kingdom established the world after Caesar's time perfectly.
