I don't think this is worth the hate it's getting. We all know male Thor will get the hammer back eventually. Chill out.
It's intentional pandering and ruining a male superhero at the height of his popularity and on the back end of an epic and well written series which is now derailed so that a female Thor story can be told rather than the male Thor fans want to read. It's very much worth the hate, I assure you.
