why doesn't Brad Bird want to do an Incredibles sequel??
and if not a feature film, I would have thought Disney might have done a 2d animated tv show to continue the story.
Ultimately Incredibles is his baby and Pixar will never move forward without him in doing a sequel. The argument I'll make which might be a reason for the lack of sequel is that Incredibles really isn't a story that needs continuing or to be franchised. It's really the story of a family struggling to live a normal life and by the time the films ends they get exactly that.
