On one hand, means unlikely we'll get another TV series based on Sonic's third movie.
On the other hand, what they expect from making a Knuckles TV series with secondary human character as protagonist?
Cost saving, that's what I expected.
With human character as protagonist they could fit the CGI effects into the limited TV series budget.
It's a bold direction to go. Instead of the actors trying to emulate the existing characters, have them be more natural to the role.
Many games-to-movie adaptation failed with this approach. Hopefully not with this one.
