So with New Adventures, the idea of He-Man and Skeletor going into space is great. It's fine that all the old Evil Warriors are gone (numerous 80s stories had already done this, such as the mini-comics, or just kept Beast Man and Evil-Lyn around). The Skeletor/Flogg and Skeletor/Crita dynamics are great. Slush Head, Optikk, etc look as cool as any of the weirdos who were already in MotU.
One problem is that Primus is lame. The only good thing about it is Mara not liking He-Man at first because her people believe in pacifism, then warming up into a bikini-clad hair mace fighter.
Second problem is ignoring everything MotU had already established about space, like Marlena and the existence of an intergalactic Horde.
