>>9916593New Adventures had a shortage of good characters and a conceptual problem.
On the bad guy side, the Skeletor/Flogg and Skeletor/Crita relationships work well, and Slushhead is a good character.
For good guys, there's really only He-Man himself and Mara's character arc.
Conceptually, it was dumb for a space adventure to require time travel when there's already a galactic empire called the Evil Horde. Just have the Denebrians be the Denebrian branch of the Horde and Primus sends a ship to Eternia because it successfully repelled an invasion.
