The Venture Bros. The world building was massive for a show that started out as a Jonny Quest parody complete with supervillains/heroes, spies, politics between these groups, a deep history spanning over a century and mysterious characters that hinted at a deeper story. They were planning to do an arc using a Magneto analog voiced by Matt Berry and how he was dethroned by David Bowie. The entire series was written by two guys so it’s likely the reboot’s quality would still be great.
