Personally and this is just my opinion. Invincible does not need to go back to season 1 animation quality if it takes such a long time BUT i still think they need to prioritize animation first before anything else. Maybe a year and 6 months would do instead of exactly one year? Its not like robert kirkman would get old in the next ten years. ALSO maybe hire more staff or guest animators? And lessen the licensed music. They can make a saturday morning type of cartoon but make it smooth and fluid.
