For my first blog post, I'll ask, what do you think we can expect from Thor: Ragnarok?
For a start, we can forget the notion of the cyborg-clone Thor from Civil War popping up: Feige and Christopher Yost (on Twitter) confirmed we're talking about Ragnarok, an event that involves everyone potentially dying.
Furthermore, Yost and Craig Kyle headed production on the wonderful The Avengers: Earth's Mightiest Heroes. The worst part of its cancellation was that we'd never see it complete its Surtur storyline. You don't think both writers would resist the chance to write that story in a movie? It's a heck of a consolation prize. Fans might ponder if this means we'll see the Enchantress enslaved by Surtur?
Furthermore, Feige wants Ragnarok to do for Thor what Winter Soldier did for Cap. This means a couple of things: firstly, the film has to be a tremendous stylistic shift from its predecessors. Obviously TWS was set 69 years after The First Avenger, which was why it had a modern aesthetic and almost entirely different cast, so how can Ragnarok better distinguish itself from The Dark World, which featured an attack on Asgard from an ancient enemy who wanted to extinguish the universe? (They basically cribbed Surtur's need for the Eternal Flame with Malekith and the Aether.)
It's important Doctor Strange will be released before Ragnarok if it wants to delve into supernatural characters and elements like Hela. Contrastively, the film might distinguish itself by going more sci-fi than ever in GOTG's wake, having Thor fly through space with his hammer and adapting the actual Beta Ray Bill storyline with Surtur. I'm sure Jane would love Thor taking her to more planets.
Secondly, it will have an obvious impact on the universe's events, just as the fall of S.H.I.E.L.D. led to Tony Stark creating the Ultron Sentries. This is obvious: the Tesseract and the Infinity Gauntlet are in Asgard, and if the planetoid is razed or smashed to pieces, Thanos can easily walk in and recover them in a post-credits scene or even the actual ending. The latter is quite probable given Thanos has already made an appearance in the main body of a film.
TWS also received very good reviews because viewers saw it as a commentary on the NSA and the balance between freedom and security. Could Ragnarok explore the impact Thor would have on world religion with people knowing of Asgard's existence, à la Dan Jurgens' King Thor series. Admittedly that stuff may be better served in a future film with the Asgardians living on Earth, but it's worth considering if Marvel wants to go genuinely deeper.
