Space Cases only lasted 2 seasons, but unfortunately all the actors have aged too much to go back to their roles. Some fans I've seen wanted the original actors back regardless since it would then take place when they're near the end of their journey (which takes a little more than 7 years). Some others wanted a remake, which would mean new actors. I'm completely in the middle about either one.
On the other hand, cartoons don't have to worry about aged actors as much and it would it great to see more new episodes of Mike, Lu, and Og.
