Some people may disagree with me completely on this, but my opinion is based on my lifelong love of MOTU. He-Man definitely exists successfully on 2 different levels and people love the character for different reasons. You can basically sum it up by either the cartoon OR the box art on the toys. The cartoon was campy and very charming, it is a wealth of nostalgia. The card art was amazing barbarian style fantasy art that fueled my imagination just by looking at the pics.
Long story short, (and here's where my opinion come in) He-Man needs a very basic barbarian look and feel like the box art had to work as a realistic take. You just need a buff warrior with fur boots, fur loincloth, metal wrist guards, metal chest harness, sword, axe and shield. A major part of He-Man's character is that he isn't flashy or "geared-up", it's that he relies on strength. This is why there was such a disconnect with the look of the Dolph Lundgren version and the 2003 version of the character.
It blows my mind that so many people in 2018 making toys don't get this concept. You can make all of the other characters have updates and make them more and more elaborate and flashy. You can give Man-At-Arms more blaster rifles, more maces, axes, helmets, etc. and it works, the same with Trap-Jaw, Zodak, etc BUT start putting capes, rifles, pleather skirts, etc on He-Man and you start to lose his essence.
Phicen should've been making knock-off MOTU characters for years by now. If you're going to try to do realistic takes on muscle bound heroes, you shouldn't want them to have giant ratcheted knee joints and arm plugs
