This is a terrible situation all around. On one hand, I always wanted new Boondocks just so it could erase what happened with season four. But on the other hand, you can't just replace someone like John Witherspoon. A lot of Granddad's character felt like Witherspoon in animated form.
Add to the fact that HBO Max comes out this month, the announcement was made almost a year ago and we've heard absolutely nothing since then means that something happened to the reboot. Either it's being held up for a while or they're not going through with it anymore.
This show is cursed, honestly.
