I agree 100% with everything you posted (including the spear, what a genius weapon). I wanted to add a few things I really enjoyed.
First off, Thor and family. I LOVE that they made Thor such a wonderfully flawed character. Alcoholic, anger problems, has an abusive father? Fuck, take the godhood power out and he's just like an insane amount of regular people in the world. I really felt bad for him, because he wanted things to get better, but didn't think it was possible until right before his own father killed him.
Also the Tyr shit. FUUUUCK that got me good, completely out of left field. Phenomenal setup by the creative team, Jesus.
I don't think any game has made me tear up so much in such a short period of time. But pretty much from the time Brok got stabbed until the credits after his funeral, my eyes were averaging out to a slow trickle. Incredible story telling.
Freyr's death felt pigeonholed and pointless, tbh. It didn't have much impact. To be brutally honest, I think he was the character I connected with the least.
And Ironwood. There was such a buildup about it being this super secret place that Odin didn't know about, and then basically never mentioned again. Along with Angrboda, it feels like an entire chapter was edited out of the story. Like, why even go through all the trouble of making that area and character?
Still thoroughly enjoyed it, 10/10. I'll probably work my way through the side stuff eventually.
EDIT: Oh yeah, Sindri. Just... Damn, man. He and Brok always teleporting off-screen has been a staple since the first game. Even the other characters occasionally comment that they don't understand it. When he teleports away in full view of the camera right after Brok dies, my immediate thought was, "Oh. Oh, fuck." But from that moment on, Sindri just doesn't care anymore.
They were always the comic relief, there to laugh at or with, but never one to make me feel feelings, what the fuck? Plus Sindri almost instantly changes, from a complete germaphobe to still having his brother's blood on him at the funeral, days later. That man is completely and utterly broken, and it was portrayed so heartbreakingly well.
