I'm not sure why people think Thor touring the Nine Realms would work. You need time to establish worlds and the characters and their motivations. Having Thor skip around from one realm to another would make each trip too brief and ultimately uninteresting. I'd rather have them concentrate on only a main bad guy and maybe some henchmen/supporting characters. Develop them and make them interesting.
They don't need to spend a lot of time developing and defining each of these worlds and their inhabitants. Hell, it's World of Warcraft; Dungeons & Dragons; Skyrim. Dragons, trolls, elves, giants, dwarves. What else do you need to know?
Think of any one of the LOTR movies, and think of each setting as a separate world. The Shire & Bree; Rivendell; Lothlorien; Moria; Isengard; Parth Galen. Think of each area as a separate world with its own inhabitants --- Hobbits in the Shire, Elves in Lothlorien, Dwarves & Balrogs and Trolls in Moria; Orcs in Isengard. TTDW will likely take a similar course.
