So... the Sorceress is dead, Orko is evil, Teela is a borderline nudist, Castle Grayskull and the power sword are useless relics, and He-Man IS the Power!
Those old Star Comics from the 80s are suddenly looking pretty good right now.
Seriously, though, I don't mind the changes too much as long as they're contained to this comic (I would hate to see this play out in a television series or movie, which would be seen by a much larger audience and become the new direction for the property overall). This comic almost feels like someones fan fiction to me and that's fine, but the violence and gore are a real turn off and I likely won't continue with this series if that continues. I think you can still imply violence without turning the book into a bloodbath.
