I don't know what screenwriters aspire to.  Clearly, it depends on the screenwriter, but I wonder how many lay awake at night and think to him or herself, "I wish I had the chance to re-adapt the cartoon 'Masters of the Universe' into a live-action film because I could really capitalize on some goofy nostalgia."  Whether Evan Daugherty had that dream or not is unknown but he will be coming on board to rewrite Justin Marks' (who, as the go-to guy for "Street Fighter", "Voltron", and "Shadow of the Colossus" probably did have that dream) script for "Grayskull" because you don't want to your movie about He-man to sound un-cool with a title like "Masters of the Universe". 

According to The Hollywood Reporter (who act like Daugherty committed the artistic crime of the century by getting this job; he's not adapting Faulkner, here), Warners sees the big-screen version as a gritty fantasy and re-imagines Prince Adam (He-Man when he calls on the power of Grayskull) as a soldier who sets off to find his destiny, happening upon the magical world of Eternia. There, Skeletor has raised a technological army and is bent on eradicating magic.

I'm sorry.  You lost me at "gritty fantasy".  It's Masters of the Fucking Universe.  You can't just have fun with it?  He-Man had a Prince-Valiant haircut and wore furry underwear.  Who wants a "gritty fantasy" from that?  Who is so emotionally retarded that they need their silly property about a man who cries out "I have the power!" to be deadly serious?
