Yeah I agree.
Kinda going off that, it did bum me out a bit that their answer for how to fix Thor was basically just turn his franchise into Guardians of the Galaxy .5. From the way they handled the humor, the tone, the action, etc. it just really came off as Guardians lite. Yeah I know Thor's own source material has had that type of sci fi before, Ragnarok was a good movie, and it worked out phenomenally for the MCU and the character; but I feel like if it wasn't for Guardians success they wouldn't have gone that way with it. And we have enough sci fi centric SH stories and heroes. But that's just imo
To your actual point, yeah I wish they leaned more into the Norse stuff as you mentioned and made it a fantasy adventure series. With the first Thor, they did try and explain the whole science (sci-fi) and magic (fantasy) aesthetic and I think for the first movie it worked. But starting with TDW and for sure with Ragnarok they leaned more to the sci fi side. I wanna see stuff like the Midgard Serpent, light elves and dark elves who actually use bows and swords, etc.
I think Thor 2 should've been a quest across at least one of the realms we haven't seen. You know there's some mcguffin and they either have to find it or destroy it they have to travel across Vanaheim, Alfheim, or wherever to complete the quest.
Thor is in an interesting place. Reception wise he's better than he's ever been. But:
-Odin dead
-Frigga dead
-Main timeline Loki dead (although I have a feeling Lady Loki will be introduced into the main timeline sooner rather than later. Also if she will appear I bet Jodie Comer will get the role.)
-Warriors Three dead
-Sif MIA/persona non grata. Maybe she appears in Love & Thunder
-Heimdall dead
-Ragnarok happened
-Asgard the planet/realm destroyed
-Most Asgardians dead
-The Destroyer made into a joke...and dead
-Malekeith, one of Thor's primary enemies, was given a horrible treatment...and is dead
For sure, there's still a lot of ground that can be covered regarding the Thor franchise, but it seems to me like they've knocked off a lot of interesting pieces. Especially for going the fantasy/mythological route down the line.
@Iceman is right they can go back and explore that stuff, but I feel like with all those pieces removed they won't. That and MCU Thor has had way more success with sci-fi than the more fantasy stuff.
I feel like both Thor and Wonder Woman kinda dropped the ball at more deeply exploring their cultures in their respective series. One of my huge gripes with Wonder Woman was how the Amazons were handled. And looking back at Thor I wish we would've spent more time with Warriors 3, Heimdall, and Asgard. Especially if they wanted me to feel something when they died or were destroyed. We'll see what they do though
