It's not fan service. It's just a Thor story in which another person uses his hammer, like a horse-faced alien did it, and like a frog did it before her.

Why does it have to be a woman? Why not? The worthiness enchantment requires the Mjolnir's user to be worthy, not to have a penis. A woman with the power of Thor (more than two panels) in the Marvel Universe is something that never happened, it's something new.

It's stupid to call this fanservice.

And as you believe this is fanservice, I guess you didn't get to read the whole article, or even cared to have an informed opinion. Thor won't become a female. Thor Odinson will still be around, he will no longer be worthy, but he will still be there with the Avengers using the Jarnbjorn. This is a new character who was worthy of carrying Mjolnir.

Even though "Thor" is not a title, it's kind of a habit to call "Thor" whoever is holding the hammer. Eric Masterson was called Thor, not Eric. Beta Ray Bill was also called Thor.
