Asgard was the neatest part of Thor, as far as worldbuilding went, so I'm really excited to see more of it.

Agreed!

I hope Sif and Darcy get lots of screen time, too. They're both fun, in their different ways.

I haven't read any of the original lore or the comics, though, so pretty much everything I know is what I've seen in the movies. Any insights to what goes on beyond the movie(s) is welcome!
