I'm seeing the casting for this - Idris Elba, Jared Leto - and I think I get it; they are gonna THOR this movie. Imitate that franchise as much as possible.
They are going to need every edge they can get, to get a wide audience for a toy line that sounds like it was created by a pre-schooler.
I suppose it's fitting. He-Man And The Masters Of The Universe is a roundabout ripoff of DC's New Gods series, which was in itself taking the mythos of Marvel's THOR and putting it into a more science fiction setting.
