These issues are heavy on the Asgard mythology stuff. Mangog is the villain.
I like the way Sal Buscema draws him. It’s very different from Jack Kirby.
The issue #250 is, surprisingly, not a double-sized one or a big event.
One interesting development is that Jane Foster now turns into Sif the same way Don Blake turns into Thor.
The story in these issues is fine as far as Asgard stories go. I prefer my Thor with a good helping of Earth or outer space. It’s nice that The Warrriors Three are becoming regular parts of the stories, though. I always enjoy them.
Marv Wolfman got plot assistance credit.
