Exactly, and eventually he regains his worthiness, takes back the mantle of Thor, and now Jane is becoming the Valkyrie.
If you read enough mainstream comics, you realize that they never change anything. They are simply quite good at producing the illusion of change. But at some point, they always fix the toys and put them back in the box for the next wave of creators to play with.
The movie Valkyrie thing is... disappointing, but not completely out of character for what they've built. She was a pretty ardent man-hater in Ragnarok, so to me it's not totally out of left field. But mostly life is too short to give a damn about lame shit like that. It won't prevent me from enjoying the film, as I pretty much have to put these movies in their own silo anyway, as they differ far too much from the "real" stories in the comics to matter in the grand mythology of the characters. I treat them like a classic "What If " or Elseworlds stories, and they can do whatever crazy shit they like in those.
